This update cleans up how notification data is passed through mail-related features, reducing edge-case errors and avoiding unnecessary database lookups. It also refreshes naming, documentation comments, and performance test expectations across related apps as preparation for future email-like recipient improvements.

Consider 'msg_vals' propagated through layers of notification is False
by default, not sometimes None or False. Add fallback to avoid trying
to access keys of False/None. Correctly update some old writing. Be
sure to use a writing that allows to skip message access in simple
cases, as it was build to avoid useless queries.

Update overrides docstrings: use comments to avoid overriding the base
docstring.

Rename / remove outdated code. Update some left query counters.

Reformating Indian localization payslip report

Shop floor workers can now manage component, byproduct, and production registration more directly from the related stock movement instead of individual line links. This simplifies the workflow, reduces behind-the-scenes synchronization issues, and improves barcode scanning for products and lot or serial numbers.

We remove the link between quality.check and stock.move.line for:
- component registration checks
- byproduct registration checks
- register production checks

Instead, we link the quality.check directly with the stock.move, and show a table of move lines on the check for the user to manipulate all at once.

This change allows us to get rid of a lot of synchronization code related to the continue consumption or synchronization between quality.check and stock.move.line.

We also add a bunch of improvements to barcode scanning in the shop floor.

Payroll users can now reset payslips to draft directly from the payslip list, making corrections faster without opening each record. The available list actions were also reordered to make common payroll tasks easier to find.

The update stops sending an unused company identifier in some background request data. This simplifies request handling without changing visible behavior for users.

* = account_accountant, web_studio

The current_company_id key is not used on the server, so it does not need to be sent in the context. Note also that, only the web_search_read function sends this key.

The mail attachment viewer now shows a tooltip explaining that the popout action opens a PDF in a separate window. This makes the control easier to understand and helps users choose the right viewing option without confusion.

Add a new tooltip on the popout to open a pdf in a different window.

The Discuss interface receives small visual refinements that make conversations easier to scan, including better spacing, clearer unread indicators, and cleaner message dates. The member list now opens by default and remembers the user's preference, helping teams see who is online and encouraging collaboration.

Some style tweaks to discuss for improved readability and usability:

1. Slightly more vertical spacing between discuss sidebar items.
   -> Motivation: discuss sidebar felt too crowded, which was a bit hard to see group of avatar and related conversation name.
2. `.rounded-3` on category and channel actions rather than `.rounded-circle`
   -> Motivation: rounded square match rest of UI better, and makes hover effect slightly more visible.
3. Consistent spacing in-between category and channel actions, less spacing when next to badge counter.
   -> Motivation: spacing was too big and inconsistent.
4. Composer in discuss app is slightly lower.
   -> Motivation: felt too high compared to other chat apps
5. Member list is open by default in discuss app. Its default opening state is saved in local storage, thus preserved when open.
   -> Motivation: better visual of online members, incite for more communication between members, and also discuss feels more feature-complete.
6. Discuss sidebar unread indicator (small dot) is slightly more visible (opacity 35% => 50%).
   messaging menu important indicator is more visible (opacity 50% => 75%)
   -> Motivation: more visible while still not too distracting, the new opacity fits more with the rest of UI.
7. Message datetime does not show year if same as current year
   -> Motivation: reduces UI noise a bit for 2 days-old messages.
