The website information page now links third-party localization modules to the correct author website instead of a generic Odoo page. It also hides the Odoo version from public visitors and simplifies the page behavior, reducing unnecessary exposure while keeping the page useful for attribution and SEO.

[IMP] website: show author website for localization on /website/info

[FIX] website: fix the /website/info page

A redundant and fragile internal test in the mail area was removed. This reduces maintenance risk for developers without changing the product experience for users.

fieldmany2many tags email test is redundant and error prone (multiple callbacks
relying on nextTick to be called in the right order). Let's remove it.

Event pages with little or no content now place sponsor icons closer to the footer instead of directly under the page title. This creates a cleaner page layout and keeps sponsor branding aligned with the intended spacing on default event pages.

PURPOSE:

When a website_event with a submenu is created, some default pages
contain an empty space to lower the footer (see odoo/odoo#89602).
On these pages, the sponsor icons are now at the bottom of the page,
on top of the footer, instead of just below the page title.

This update reorganizes how subscription sales information is passed from templates to customer orders. It keeps related logic closer together, making the system easier to understand and maintain without changing day-to-day user workflows.

That way, the method overrides are grouped with the new fields to 
propagate between template lines/options and order lines/options.

Eases code comprehension and maintainability.

This update streamlines automated tests for the Documents Spreadsheet area by removing unnecessary waiting steps. It helps developers get feedback faster, reducing test run time by about 20% without changing user-facing features.

Belgian payroll schedule changes no longer close employee contracts unnecessarily. This keeps payroll records aligned with the newer automatic contract expiration behavior and helps avoid incorrect contract status changes during schedule updates.

Adapt payroll tests to the contract auto-expire introduced in
odoo/odoo#90714.

The Solar email theme now uses a coupon code block that can be edited directly in the email editor. This removes text placed over images, making campaign templates easier for users to customize without design workarounds.

The Solar theme contained a custom coupon code snippet with text over image.
In an effort to remove all text over image elements (because users are currently unable to edit text placed over an image with the email editor), the snippet has been replaced by a version of the original coupon code snippet.
