## [I18N] account_reports, hr_payroll: revamp AU translations

We update some translations to be more aligned with local lingo.

Purpose:
    Calculations in SA localization are done based on 30-day month basis accourding to the law.
    So, in this task we add 30 day pay schedule to allow 3 options:
        - Wroking days => Set schedule pay as monthly and calendar as a normal one
        - Calendar days => Set schedule pay as monthly and calendar as a full week one
        - 30 days => Set schedule pay as 30_monthly and calendar as a full week one

Current behavior:
- changed the hardcoded value of 30 in salary rules to use number of days in the month accourding to the schedule pay
- corrected the computation of gosi rules to include all unpaid days in calculation
- changed some rules to use the correct category of `SA_ALW` instead of all allowances
- added a rule for deferred amount for the cases where the the employee took a full unpaid month in a non 30-day month 
- added tests for 30-day pay schedule
Note that changes in tests are mainly because we are using working days instead of hardcoded 30 days per month

Task: 6042556

Currently, if you refund an order made on the customer account with the customer account as well, you can still see the order in the list of orders to settle.

Steps to reproduce:
-------------------
* Open shop
* Make an order using the customer account for a customer, don't invoice it
* Refund one of the order using the customer account, don't invoice it
* Make a new order using the customer account
* In the customer list, find the customer used and select "Settle Orders"
> The 2 orders are present in the list

Why the fix:
------------
Originally the list would only show the orders for chich the customers have due (>0).
https://github.com/odoo/enterprise/commit/bf4b6043b999b4a081b1afa73fc4113bf4db28f8

But recently the code we also see the refunds in the list as well.
https://github.com/odoo/enterprise/commit/12af23d5382e972facfaa999e4c5ab30c97e8d1f

However this new behavior is not visible if, with the refund, the customer account temporarily falls to 0.

So currently we have some refunds that impact the amount to settle and some that don't. Originally we were thinking that either we should show all refunds in that list (given they use the customer account) or we shouldn't show any as it was previously. Both solutions are not ideal.
* Showing them all would get the list bigger than it is and would require the customer to select the order and its refund(s) and settle them together. Since refunds are not usually done right after the order they would not be close it that list. However this solution would enable the option to remove the orders from the list requiring a few step from the customer.
* Showing none isn't idea either with this use case as it means that we still see orders that were cancelled out by their refunds. To remove to order the customer has two options. Either going backend and searching the order and its refund(s)
and invoice them, either settling the order but that means that now there's money deposited on the customer account.

Any of the two option isn't perfect a it still requires manual intervention from the customer and wouldn't work on previous data. Creating a server action to correct those data wouldn't have been feasible either.

Instead, the approach we're taking is the following: When loading the list of order to settle we want to remove the orders and the potential refunds were the customer account is evened out.

We only need to look at the orders of the partners that contains refunds for which the customer account was used. If the sum of the transactions made on the customer account is 0 we can say that the order and its refunds have cancelled out each other (in terms of customer account) and we don't show them if the list of orders remaining to settle.

### Steps to reproduce:

- In the settings Enable: Multi-steps Routes, Packages
- Put your warehouse in delivery in 2-steps
- On the Pick operation type in the barcode tab disable: "Allow extra products"
- Create two storable products P1 and P2
- On P2 > On hand > Update Quantity > New
- Create a new line in WH/Output with a package POOK for 1 unit
- Create a new internal transfer for 1 unit of P1 using the pick operation type so that the picking goes WH/Stock -> WH/Output
- Set the quantity of the move to 1 unit and go to the barcode app
- Open the Pick > Scan WH-STOCK > Scan P1 > Scan POOK
#### > An error is raised: This package contains extra products and extra products are not allowed on this operation.
#### Expected behavior:
The package should be set as result package.

### Cause of the issue:

In the `_processPackage`, a check that is done to ensure that the package scan will not add extraproduct to the picking if this operation is not allowed:
https://github.com/odoo/enterprise/blob/5e4c8ecb0c644e21755570ed59cd8f6e9f618c8a/stock_barcode/static/src/models/barcode_picking_model.js#L2024-L2035
Unfortunately, this check is done just before a possible usage of the package as package dest. And, in that case, since we do not try to add any product to the picking the check is irrelevant anyway.

## Issue
When a user sets their notification to "Handle in Odoo" (`inbox`) and a sign requested is completed, they do not receive the expected notification.

## Steps to reproduce
1. Install *Sign* (`sign`)
2. Sets the current user's notification preference to "Handle in Odoo" (`inbox`)
3. Create a sign request and send it to Marc Demo
4. As Marc Demo, sign the request
5. **The user who sent the sign request did not receive a notification to notify them that the request was signed.**

## Fix
This is a partial backport of both https://github.com/odoo/enterprise/commit/463d6a2aae536356e6dee6b902f2e881dbc4fbda (saas-18.2) and a related fix https://github.com/odoo/enterprise/commit/41395dba4fd31222f5fd9fc94a84c977cf9334f9 (19.0). Before the first commit, users would not receive inbox notification when sign requests would be completed.

## Note to reviewer
The issue only occurs in 18.0, as it is fixed by https://github.com/odoo/enterprise/commit/463d6a2aae536356e6dee6b902f2e881dbc4fbda in 18.2, but we can backport the fix from https://github.com/odoo/enterprise/commit/41395dba4fd31222f5fd9fc94a84c977cf9334f9 from 18.2 to 18.4 if desired.

## Current behavior:
In the Project's app, switch to Gantt chart's view, when changing the deadline of a single task by shrinking its right edge, the server throws `ValueError: max() iterable argument`` is empty when calling end_date = max(candidates.mapped(stop_date_field_name)).

## Steps to reproduce:
1. In version 19.0 and above, install Project app
2. Create a project and only 1 single task
3. Switch to Gantt chart view
4. Try changing the deadline of a task by dragging its right edge
5. Observe that extending the task's deadline by dragging to the right works fine, but shrinking the deadline by dragging to the left will cause server to throw RPC_ERROR: Odoo Server Error and ValueError: max() iterable argument is empty.

## Cause of the issue:
- A task with NO successors will cause candidates gathered via dependency_inverted_field_name to be empty.
- The empty candidates recordset then get called by max(candidates.mapped(stop_date_field_name)), which is the reason causing error message ValueError: max() iterable argument is empty.

Issue
-----
There are 2 issues with USPS rest:

1. USPS packagings do not have their size UOM displayed. This leads to confusion as users input in inches but the dimensions are treated as feet.

2. USPS returns the same rate regardless of the package type.

Steps to reproduce
-----
- Set USPS up
	- Open the Package Type form > go to its' Dimensions tab

> Issue 1

- Set USPS up (domestic)
	- Select a `Domestic Rating Indicator` (eg LF - Flat Rate Box)
- Create a SO with some product
- Open the delivery widget and add a rate with USPS
	- Discard the changes
- Go to the delivery method and change the rating (eg SP - Single Piece)
- Go back to the SO
- Open the delivery widget and add a rate with USPS

> Issue 2, rate is the same as before

Issue 1
-----
By default, there is no displayed UOM on the form because of

https://github.com/odoo/odoo/blob/38c737c2a4cc29b48235a100cfa9d6152af73826/addons/stock_delivery/models/stock_package_type.py#L20-L33

We can change this behaviour for USPS specifically as done in Envia

https://github.com/odoo/enterprise/blob/20cc61e69aa3f6a59de1e962b25ce11fa402bf22/delivery_envia/models/stock_package_type.py#L37-L46

Issue 2
-----
In `usps_rest_rate_shipment`, we request rates for every package of the delivery, which we receive as lists. We then iterate over the list to find the rate matching the `mail_class`. The problem is that this only filters over whether the delivery is domestic or international. We don't filter based on the actual service selected on the carrier (`usps_domestic_rating_indicator` for domestic and `usps_international_rating_indicator` for international).

**Problem:**
On a round-the-clock (0h-24h) working schedule, shifts created from a shift template that spans more than one day get one extra minute added to their allocated time: an 8-hour shift shows 08:01.

**Steps to reproduce:**
1. Create a working schedule with a 00:00 -> 24:00 attendance for every day (24h/day, "Full Day").
2. Assign an employee to that schedule.
3. Create a multi-day-span shift template (e.g. 16:00 -> 00:00, 2 days).
4. Plan a shift for that employee using the template.
5. Observe the Allocated Time shows one minute more than expected (08:01).

**Current behavior:**
Allocated Time is one minute too long (e.g. 08:01 instead of 08:00), which throws off the customer's planning reports.

**Expected behavior:**
Allocated Time matches the template duration exactly (08:00).

**Cause of the issue:**
In `_calculate_start_end_dates`, the end of a multi-day-span shift is computed with `resource.calendar_id.plan_days(...)`. On a 0h-24h calendar each day ends at `time.max` (23:59:59.999999), so `plan_days` returns an end datetime carrying those stale seconds. The following `end.replace(hour=..., minute=...)` overwrites only the hour and minute, leaving `second=59, microsecond=999999`. The slot is therefore ~1 minute longer than intended, and `allocated_hours` rounds that up to 08:01.

**Fix:**
Resetting seconds and microseconds when rebuilding the end datetime keeps the slot aligned to the template's whole-minute boundary, regardless of how the underlying calendar represents the end of day. The hour/minute already come from the template, so the leftover sub-minute precision from `plan_days` is never meaningful and is what produces the drift.

Steps to reproduce
1. Create two customer invoices that share the same VAT tax, with a payment term granting an early payment discount.
2. Create one bank statement line whose amount equals the sum of both invoices' discounted totals.
3. From the bank reconciliation widget, select both invoices and validate in a single batch reconciliation.
4. Open Accounting > Reporting > Tax Return, switch the variant to "Group by: Account > Tax".

Issue
The cash-discount expense row shows a Net base column equal to twice the real
discount base. The Tax column is correct.

The bank-statement reconciliation paths (set_line_bank_statement_line,
set_batch_payment_bank_statement_line, _reconcile_payments) loop over each
invoice and call _apply_early_payment_discount one invoice at a time. Each
call writes one discount base line and one discount tax line on the resulting
bank entry, so when two invoices share the same tax the bank entry ends up
with two pairs carrying the same (account, partner, currency,
tax_repartition_line_id, tax_ids).

The SQL that feeds the tax report at
https://github.com/odoo/odoo/blob/d7d0efd39a65bfb6fee307b661cd2523a6b8231d/addons/account/models/account_move_line_tax_details.py#L100
matches every base line of a tax with every tax line of that tax inside the
same move. With two pairs sharing one tax that turns two rows into four, and
SUM(base_amount) doubles. The Tax column does not double because the same SQL
redistributes each tax line's recorded amount across its matched rows so the
totals still add back to the original tax.

The payment register flow does not have this problem because it calls
_get_invoice_counterpart_amls_for_early_payment_discount once with every
invoice, and that helper already collapses duplicates with the merge key at
https://github.com/odoo/odoo/blob/f3b317310b84edb073009f7d15d7fec002f3ccf0/addons/account/models/account_move.py#L5082-L5093
