This update removes obsolete internal web code and legacy test helpers that are no longer needed after Odoo's newer web framework migration. It helps reduce maintenance overhead and keeps CRM, web, mail, manufacturing, point of sale, and project areas aligned with the modern platform, with little direct impact on day-to-day users.

Enterprise test code was updated to work after older shared test helpers were removed in the main Odoo codebase. This keeps automated checks for Documents and Spreadsheet reliable without changing day-to-day user functionality.

This PR is the enterprise counterpart of odoo/odoo#129725 where we remove several legacy test helpers. We thus had to adapt some tests that were still using them.
