[IMP] mail, mail_bot: improved push notifications permission response

This commit makes small improvements on the messaging menu with
the new module `mail_bot`:

[IMP] When OdooBot has a request, it now adds "+1" to the counter of
      the messaging menu. The related preview also has a bold title,
      and displays "(1)" next to the title.

[REF] Static previews are no longer in mail_service. This was only
      used for "OdooBot has a request" preview. This logic has now
      been moved to the module `mail_bot` (was previously in `mail`).

[FIX] Title of response of push notifications permission clearly
      states whether permission has been granted or denied
      (was displaying "[Object object]" before this commit).
