Odoo now shows a clear warning icon and tooltip when a user has not set their timezone in preferences. This helps users notice and correct missing timezone settings, reducing confusion around dates, times, and scheduling.

- Icon displayed next to preferences if user haven't set timezone
- same icon next to the timezone field
- added relevant tooltip

Website debug pages will now receive standard updates when the website module is upgraded, as long as they have not been manually changed. This helps keep multi-website setups aligned with improvements and avoids outdated page structures.

Before this commit, those pages would be flag as noupdate.
If not modified, those view would not get modification on module update, which
is not logic.

Now, those view will benefit from any update. It makes even more sense since
multi-website, as those views will never get modified directly (it will COW).

This update adjusts an internal test for the website product comparison feature to use a standard tour-starting helper. It helps keep automated checks consistent and easier to maintain, with no expected change for shoppers or website managers.

Oversight of forward port.

This update aligns recently merged changes with Odoo's newer debugging setup and test organization. It helps prevent related web editor and comparison shop features from breaking after platform updates, with no expected change to normal user workflows.

https://github.com/odoo/odoo/pull/33213 introduced a new debug and new asset.
But some commits were merge simultaneously and/or forward ported from lower version.
Those commits needed to be adapted.

This update adjusts the timing tolerance used in automated planning tests so they are less likely to fail when execution is slower than usual. It does not change business functionality, but helps keep validation of manufacturing and stock-related processes more stable.

The tests relative to workcenters planning takes (sometimes) long time
to be executed. Before investigation more deeply, this commit relax a
bit more the tolerance delta in the test comparison

This fixes how Mexican electronic invoicing product code records are marked so they are not accidentally deleted when the module is updated. It helps preserve required invoicing reference data and avoids disruption after upgrades.

Enterprise version of odoo/odoo#32881

The website module’s code has been reorganized into several focused files instead of one large file. This internal cleanup makes the system easier for developers to maintain and should not change how users experience the website features.

Split class from file addons/website/model/website.py in multi files.

Make several commit:
   new file,
   move code,
   merge 
by class to keep history clean.
