This update streamlines how Odoo retrieves and manages mail data. The team has consolidated previous routes into a single, more efficient route, `/mail/store`. This change simplifies data fetching and allows for better management of writeable data parameters, ultimately improving performance and stability.

This refactor merges the two routes `/mail/action` and `/mail/data` into a single route `/mail/store` that returns store data for given fetch parameters.

Now, fetch parameters that require a read-write cursor are simply those that are in the set `WRITE_FETCH_PARAMS`, which is extended by modules that add write-capable fetch_param handlers.
