**Steps to reproduce the issue:**

- Install the l10n_mx_edi module.
- Open the Accounting app and go to Customers → Invoices.
- From the invoice line, make the Tax Object field visible.
- Create a new invoice and add a product that has no Unit Price.
- Save the invoice.
- Edit the same invoice, set a Unit Price for the product, and save it again.
- Issue: The Tax Object field is not automatically set after the Unit Price is added.

**Description:**

- In our standard code, there is a condition that skips computing the Tax Object when the Unit Price is [0](https://github.com/odoo/enterprise/blob/615a5f756d708db95e22cdbdd6e7aca72ac769ec/l10n_mx_edi/models/account_move.py#L988). This is the expected behavior.
- However, after setting a Unit Price on the product, the Tax Object is not recomputed, so it remains unset.
- To resolve this issue, I added price_unit to the @api.depends decorator so that the Tax Object is recomputed whenever the Unit Price changes.

## Steps to reproduce:

1. Install `l10n_br`, `l10n_br_avatax`, and `l10n_br_edi_fiscal_reform`.
2. Ensure that Demo mode is activated if not on Runbot.
3. Navigate to Contacts, then click into "BR Company Customer Estimated Profit".
4. Duplicate this contact, then set the following fields:
   1. Tax Regime set to individual
   2. ICMS Taxpayer Type set to Non-Taxpayer
5. Swtich to the BR Company and go to Accounting / Configuration / Settings.
6. Set up a Sandbox Avalara account and enable logging payload responses.
7. Navigate to Accounting > Customers > Invoices.
8. Create an invoice with:
   1. Customer set to the copy created earlier.
   2. Operation Type set to Sale of Goods
   3. Document Type set to 55
   4. Payment Method Brazil set to Money
   5. Presence set to Present
   6. One sales order line with:
      1. Regular Consumable Product
      2. quantity set to 1
      3. price set to 100.0
9. Confirm the invoice.
10. Navigate back to Accounting > Configuration > Settings to view the response from Avalara. The customer will have the CFOP 6102 instead of CFOP 6108.

Explanation:

PR #97845 introduced `_l10n_br_deep_clean_dict()` to remove falsy values and empty dictionaries from the payload we send to Avalara. This fix was applied as broadly as possible to prevent excessive if statements.

However, if the falsy values in taxSettings of the customer are not communicated, Avalara will assign the customer to an incorrect CFOP.

**Problem:**
On a website with rental planning enabled, a customer can book a planning-backed rental product through eCommerce even when no planning resource is free for the requested window. The cart lets them increase the quantity past the available capacity and proceed all the way through checkout without any availability gate.

**Steps to reproduce:**
1. Install `website_sale_renting_planning`.
2. Create a planning role with `sync_shift_rental` and one resource.
3. Create a service product with `rent_ok=True`, `planning_enabled=True` and the role above.
4. Pre-book the resource for some window via a `planning.slot`.
5. From eCommerce, add the product to the cart for the same window.
6. Proceed to checkout/payment.

**Current behavior:**
The cart is considered ready, no warning is shown, and payment can proceed even though no planning resource is free for the chosen period.

**Expected behavior:**
The cart should be flagged as not ready and pre-payment validation should refuse to confirm until the customer picks a different date or quantity.

**Cause of the issue:**
`sale.order._available_dates_for_renting` in `website_sale_renting` is the documented hook for "stock availability" gating of the cart and pre-payment flow (called from `_is_cart_ready` and from `_check_cart_is_ready_to_be_paid`). `website_sale_stock_renting` overrides it to apply a per-line stock check, but
`website_sale_renting_planning` has no such override, so planning-backed rental services reach payment with no availability gate at all.

**Fix:**
Apply the same gating pattern that `website_sale_stock_renting` already uses: override `_available_dates_for_renting` in `website_sale_renting_planning` so that, for each rental line whose product is a planning-synced rentable service, the cart is only considered valid when at least the requested quantity of planning resources is free during the rental window (mirroring the resource and leave filtering already done by `_planning_slot_vals_list_per_sol` at SO confirmation time). This puts the gate at the same point the stock-renting flow enforces it, keeping the public cart/checkout flow consistent across rentable product types.

## Problem

When generating an export CFE (e-Factura Exportación) in the Uruguayan EDI module, invoices that include a discount line equal to the subtotal — resulting in a **total of 0.00** — were not handled correctly by the XML/CFE generation
logic.

This use case is valid and required by exporters who need to reflect the declared value of goods/services while invoicing at zero (e.g. to comply with customs or incoterm requirements such as FCA). In Uruware's validation portal, the "Descuentos y Recargos" (discounts & surcharges) section of the subtotal block must be correctly populated for the CFE to be accepted.

**Example:** An invoice with a line of 648.00 UYU and a global discount of −648.00 UYU → Total: 0.00. The export value is still declared, taxes are zero, but the CFE must reflect the discount amount explicitly.

<img width="592" height="679" alt="example_expo_invoice_discount" src="https://github.com/user-attachments/assets/aa83c158-e342-4da5-a251-fc209bbed5c4" />

## Root Cause

The CFE template (`cfe_template.xml`) and the move computation logic (`account_move.py`) did not account for the case where export invoices carry line-level or global discounts that zero out the total. The discount amount was
either omitted from the XML nodes or computed incorrectly, causing Uruware validation to fail or the discount block to not render.

## Fix

- **`l10n_uy_edi/models/account_move.py`** — Updated the export invoice computation to correctly include discount amounts in the CFE data dict, ensuring the `ValorDR` is filled with the value of the discount per line.
- **`l10n_uy_edi/views/cfe_template.xml`** — Adjusted the template condition so `MntExpoyAsim` node accepts 0 as value.

## Steps to Reproduce (before fix)

1. Create an export invoice (e-Factura Exportación) for a foreign partner.
2. Add a product line with a unit price, e.g. 216.00 × 3 = 648.00 UYU.
3. Add a global discount of 648.00 (same amount) so the total is 0.00.
4. Confirm and send to Uruware — the CFE is rejected / discount block is missing.

## Verification

After the fix, the same invoice generates a valid CFE accepted by Uruware with the discount correctly reflected in the `DscRcgGlobal` node and the discount line visible on the printed document.

## Issue
When creating a Contract Template for a Swiss company, the template does not match the version shown in the Employee's view. Also, some fields are not correctly applied when loading a contract template on an employee (e.g. `hourly_wage`, `wage`, ...).

## Steps to reproduce
1. Install *Switzerland - Swissdec Certified ELM 5.0 - Payroll* (`l10n_ch_hr_payroll`)
2. (Create and) Use a Swiss company
3. In Employees > Configuration > Contract Templates, create a Contract Template
    - Wage Type: Hourly Wage
    - Hourly Wage: Any value > 0
    - **(Notice how the aforementionned fields are missing from the template)**
4. In Employees > Employees, create an Employee
5. On the new employee's view, on the Payroll tab, click "Load Template"
and load the template created in step 3
6. **The data from the template is not applied to the employee's contract**

## Cause
The fields loaded from a contract template are listed in the `whitelist` variable of the `hr.version.wizard`:

https://github.com/odoo/odoo/blob/5c3deb11627f4d6762c4994207bd582afb96f064/addons/hr/wizard/hr_contract_template_wizard.py#L15-L30

Multiple fields were missing from the whitelist (e.g. `hourly_wage`, `l10n_ch_has_{hourly|monthly|lesson}`, ...). These fields would not be loaded from the template when applying a template on an employee.

**This commit replicates the employee's version view on the contract template and adds the related fields to the whitelist for them to be correctly applied when loading a contract template.**

### Issue before this commit:
When reverting a Guatemalan invoice (creating a credit note), the XML node FechaEmisionDocumentoOrigen incorrectly reports the EDI document's technical certification date instead of the original invoice's emission date. This causes the SAT to reject the document.

### Steps to reproduce the issue:
1. Download Accounting and l10n_gt
2. Revert an invoice (credit note) inserting a different date than the one of the invoice
3. See that FechaEmisionDocumentoOrigen report the date of the credit note instead of the one of the invoice

### Cause of the issue:
The _l10n_gt_edi_add_reference_values method extracted the date from original_document.datetime (the technical timestamp of when the XML was generated) rather than using the actual accounting date of the original invoice.

### Reason to introduce the fix:
SAT validation rules strictly require the reference date to match the exact commercial emission date of the original invoice. Fetching invoice_date directly ensures compliance, avoids timezone conversion errors, and prevents the XML from being rejected.

### Problem

`Mail: Fetchmail Service` cron aborts with `AttributeError: 'NoneType' object has no attribute 'upper'` in `l10n_cl_edi/models/fetchmail_server.py::_process_incoming_customer_claim` when an incoming customer claim DTE has no `<RUTRecep>`:

```python
dte.findtext('.//ns0:RUTRecep', ...).upper() or
dte.findtext('.//ns0:RutReceptor', ...).upper()
```

`findtext()` returns `None` when the tag is missing, so `.upper()` blows up before the `or` fallback can run. Once the cron hits such a message it re-crashes on every subsequent run and blocks the whole mailbox until the offending mail is deleted.

### Fix

Guard each `findtext(...)` with `or ''` so the `or` chain actually falls through. Empty `partner_vat` is already handled by the existing "Partner … has not been found" branch a few lines below.

### Traceback (Odoo 19)

```
File "/mnt/extra-addons/enterprise/l10n_cl_edi/models/fetchmail_server.py", line 285, in _process_incoming_customer_claim
