This update reorganizes website builder code so key editing actions can be reused by other parts of Odoo. It supports cleaner future development and easier extension of website features, with no expected direct change for end users.

This refactor adds `export` to all classes extending `BuilderAction`, allowing them to be reused or imported from other modules. It improves modularity.

This internal cleanup makes appointment, rental, and website studio builder components easier to reuse across modules. It improves maintainability and supports future enhancements without changing the user experience.
