This fix helps purchase-related stock records reuse existing system information when recalculating linked fields. It avoids an expensive lookup, improving performance during purchase and stock updates without changing user-facing workflows.

Adding this non-stored Many2many fields allows ORM to use cache in
`_modified_triggers` and skip costly search:

```
records |= model.search([(key.name, 'in', real_records.ids)], order='id')
```

Corrects how the web mock server reads and displays certain dates, including quarter-based dates and ISO week-year formats. This helps keep automated web tests accurate and prevents date-related test failures after the date library migration.

On 00e3cb74c44565b2106dba6befac2b6f8512eede the migration of the code to
parse and formate dates on the mock server from moment to luxon was
done. Two issues were introduced on that commit: Parsing a date
displayed on quarter wasn't possible; And the ISO week year wasn't used
to format the date, but it was used to parse the date, for symmetry's
sake, now the ISO week year is used on both.

The referral app’s progress bar styling has been narrowed so it only applies where intended. This prevents the shared progress layout from accidentally changing the appearance of unrelated screens, improving visual consistency across the system.

This commit fixes the hr_referral scss by conditioning the style applied on the
progress class to its own use cases.

Indeed, the progress class is a global class and adding rules to it may break
other layouts.
