The Batch Account Move Lines option in the settings is used to aggregate together the different payslips of a payrun and to create only one move with aggregated lines, per account. This is done to enforce privacy and avoid having lines for each employee in the payrun. If salary rules with analytic distributions are involved, though, the lines are not merged and we lose the anonimity.

This happens because in the _get_existing_lines funciton, that should return the lines to be merged with the input line (line), the condition for the rules that have an analytic distribution is wrong.

In particular, the condition is wrong because the
distribution_analytic_account_ids field is a recordset of the accounts, while line_id['analytic_distribution'] is a dictionary with keys that are comma separated strings of the ids of the accounts, with values reflecting the percentage.

For example, if a rule has one analytic distribution for 40% and involving accounts 13,7 and 12 + another analytic distribution for 60% involving accounts 3 and 5, line_id['analytic_distribution'] will be {'13,7,12': 40.0, '3,5': 60.0} while distribution_analytic_etc will be a recordset containing (13,7,12,3,5). To fix the problem and keep everything inline, we extract the logic to a new function, where we first unravel the ids from the keys of the dictionary and only then try to match them to the values in the recordset.

Steps to reproduce:
- Install the `l10n_es_reports` module and switch to the `ES company`.
- Go to Invoices and create an invoice with taxes, then confirm it.
- Navigate to Accounting > Reporting > Tax Report.
- From the smart button, select `Report: Tax Report (Mod 390) (ES)` and 
  choose the year as `This Financial Year`.
- Download the `BOE` file using the dropdown and fill the wizard fields 
  (e.g., Natural Person – Name: Test, Principal activity: Test, Activity Code: 12345).
- Upload the generated .txt file to the AEAT portal. (AEAT credentials are required)

**Observation:**
AEAT rejects the file with:
`Caracteres no válidos '4. Representante - Personas Jurídicas - Represent. 1 - Fecha Poder (DDMMAAAA)'`

**Root cause:**
At [1], when `judicial_person_procuration_date` is `false`, an empty string is 
written to the BOE file, resulting in blank spaces in the exported file. This 
does not comply with AEAT’s required numeric format and causes the file 
to be rejected.

**Fix:**
This commit ensures the file contains '00000000' when 
`judicial_person_procuration_date` is false, complying 
with AEAT numeric format requirements.

Steps to reproduce (singleton crash):

Create an employee in a UTC+ timezone (e.g. Asia/Shanghai or Australia/Adelaide) with an overtime ruleset containing a paid rule. Generate work entries for a period, then create two consecutive midnight-to-midnight attendances in the employee's local timezone. Creating the second attendance crashes with: "ValueError: Expected singleton: hr.attendance.overtime.line(...)".

Steps to reproduce (stale overtime lines):

With the same setup, delete the attendance after it generated overtime lines. The overtime lines remain in the database instead of being removed.

The singleton crash occurred because `end_of_day` in `_get_overtime_intervals` was computed as a naive datetime, implicitly treated as UTC. For UTC+ timezones, the actual local end of day is earlier than UTC midnight. As a result, overtime intervals were computed with a stop time extending past the real local midnight into UTC time. When consecutive attendances were processed together, these extended intervals overlapped. The `Intervals` class (`keep_distinct=True`) merges overlapping intervals into a single entry with a multi-record recordset as payload. The subsequent `overtime.rule_ids.work_entry_type_id` and `overtime.status` calls expected a singleton but received a multi-record set, causing the crash. The same multi-record issue also affected the iteration in `_set_real_overtime_intervals` and the overtime work entry loop in `_get_attendance_intervals`.

The stale overtime lines issue occurred because `_get_overtimes_to_update_domain` (hr_attendance) built its search date range from raw UTC `.date()` values instead of the employee's local timezone. For UTC+ employees whose attendance spans local midnight, the overtime line is dated in the next local calendar day. Since the domain was derived from UTC dates, that next local day fell outside the search range, so the overtime line was never found and deleted when the attendance was removed.

Solution:
- In `_get_overtime_intervals`, localize `end_of_day` to the employee's timezone before converting to UTC, so overtime intervals are correctly bounded by the local end of day.
- In `_set_real_overtime_intervals` and the overtime loop in `_get_attendance_intervals`, iterate over individual records from potentially multi-record `Intervals` payloads to avoid singleton errors.
- In `_get_overtimes_to_update_domain` (hr_attendance), localize check_in/check_out to the employee's timezone before computing the date range so overtime lines for dates that only exist in local time are correctly included in the delete-and-recreate cycle.

: appointment{_google,_microsoft}_calendar

This is a revert commit of [1] reintroducing the
appointment_microsoft_calendar module, as we bring back the
synchronization onboarding banners on the appointment.type
form view that were removed in [1]

- A banner includes a shorcut to setup / connect google /
outlook external calendars as well as an informative message.

- A banner is a warning banner on staff users without
active synchronization in the case of google_meet set up
on the appointment, as those will not have a google_meet
link correctly added to their meetings.

Note: as the original commit removed the whole module
appointment_microsoft_calendar, the revert would also
reintroduce i18n files. To allow a clean module reintroduction,
we do not keep them in this revert commit.

In a separate commit, reintroduce the helper for the field
event_videocall_location.

Task-5969306

This commit aims to provide better support for contract changes that happen in the middle of a pay period.
It has a few impacting changes, notably:

1) Payslip calculation sequencing
As of now, all payslips of a same payrun have their line calculated all at once. While this is better for performances, it has a negative effect when a single employee has multiple payslips in the same payrun.
In such cases, we may want or need for the payslips to know what was already calculated in the same payrun to avoid overpaying contributions or allowances that have caps.

To solve this issue, we now group payslips by employee, sort them chronologically, and evaluate them in horizontal "layers":
  - Layer 1: Computes the 1st payslip for ALL employees simultaneously.
  - Layer 2: Computes the 2nd payslip for the subset of employees who have one, etc

2) More tools in HK payroll to support these cases The payslip rules now have a `l10n_hk_payrun_totals` dict that contains the total amount already reported in previous payslips of a same payruns for a selection of rules that needs it. We also provides a `worked_days_prorata_rate` which gives the ratio of worked days vs unworked days in a month for cases where we need to adjust amounts based on that ratio.

3) Rule updates
The last part of the fix requires some updates in a few rules that are fixed amounts/not based on the wage and ends up being counted double in our use case. These rules will now take into account already computed amounts as said above to avoid going over the limit.
In most cases it will only affect that specific use case, with a small exception for fixed mpf voluntary contributions, which have been updated to be prorated based on the worked days in the month.
