The push notification feature now uses the browser's current storage mechanism instead of older legacy storage methods. This keeps the implementation cleaner and better aligned with modern browser behavior, with no expected change for end users.

This commit removes the legacy storage (localStorage and sessionStorage) and replaces it with the storage coming from browser.

Part of task-id 3439226

This update removes unused options from the internal record-saving process across several Odoo apps. It simplifies the codebase and reduces maintenance overhead without changing expected user workflows.

Remove unused parameters from record save method :
- stayInEdition
- useSaveErrorDialog
- savePoint
- force
- closable
- saveAndNew

This update removes outdated internal code used across several Odoo Enterprise apps and updates related screens to use the newer structure. The change helps simplify maintenance and reduce technical debt, with little expected impact on day-to-day users.
