This update standardizes the display of percentage fields within the Swiss payroll module. Previously, percentages were represented as whole numbers, which has now been changed to fractional numbers (ratio of 1.0) and displayed using a dedicated percentage widget. This ensures consistent and accurate reporting for Swiss payroll calculations.

Generalised the definition of fields displayed as percentages in the
Swiss payroll ocalization to be fractional numbers (ratio of 1.0) rather than
whole numbers (ratio of 100.0), and used the percentage widget to
display them all.

This update improves the way attachments are handled within the website helpdesk module. A recent change allows the `insert_attachment` function to return attachment IDs, which are now correctly passed back to the website helpdesk override. This ensures attachments can be used effectively and avoids potential conflicts.

Following the changes in [PR](https://github.com/odoo/odoo/pull/219914), `insert_attachment` now returns 
`orphan_attachment_ids` so they can be reused outside the method. To
avoid return-value conflicts in the website_helpdesk override, we return
the result of the super call here.

This update restricts the use of the `DotDict` class to testing environments only. Previously, its improper use could lead to unexpected behavior. This change enhances stability and reduces potential issues in production code.

The `DotDict` class can produce unexpected behaviour if used incorrectly.
This commit moves this class so that it is only used in tests.

This update resolves an issue related to the format of Client IDs used in the payroll module, specifically for the Belgian HR payroll (l10n_be_hr_payroll). The change allows for both the old and new Client ID formats (with and without a hash) to be processed correctly, ensuring seamless integration with external systems.

This update resolves an issue where the l10n_ar_edi module fails to function correctly after upgrading. The fix ensures the module has a direct dependency on the currency_rate_live module, which is now correctly installed, preventing an error related to a missing currency provider setting.

The module [adds](https://github.com/odoo/enterprise/blob/master/l10n_ar_edi/models/res_company.py#L64-L67) selection values to field `res_company.currency_provider`, a field [defined](https://github.com/odoo/enterprise/blob/3dc72c9641f62990f5ed3c0ce0cda5ed7b6784a1/currency_rate_live/models/res_config_settings.py#L194-L200) in module `currency_rate_live`, but althouth it is auto-install, it's not a direct dependency, which can trigger errors.

To reproduce:
- Install `l10n_ar_edi` in 19
- Uninstall `currency_rate_live`
- Upgrade to saas~19.2

It will break with
```
AssertionError: Field res.company.currency_provider without selection
```

This update resolves a minor issue within the l10n_ch_hr_payroll module, specifically correcting a file name that caused a potential error. This ensures the payroll calculations function smoothly and reliably, preventing disruptions to payroll processing. The change is a straightforward fix with no impact on core functionality.

This update fixes a misunderstanding regarding the date a W4 form is filed with an employer. Previously, the system incorrectly tracked when the form was filled in, rather than the actual filing date. This change ensures accurate reporting and compliance related to US payroll.

This field is about when the W4 is filed with the employer, not when it's filled in.

This update fixes an issue where the SEPA payment file version was incorrectly displayed as empty in the Odoo interface. The fix ensures the correct 'PAIN 09' version is generated, aligning with the underlying database data. This improves the accuracy of payment file generation.

https://github.com/odoo/enterprise/commit/80f9f966d7db793ae82e65c76514323cb10e34ab tried to fix the issue, but assumed the field would be returned empty by the ORM when the value was inconsistent with the db. It's not true: it returns the database value ; only the UI shows the field as empty.
