[vttranlina]

This is the same with James https://github.com/linagora/james-project/issues/4679 but integrated for tmail-backend

• [x] Firebase
• [x] As a delegate I should not be able to manage PGP public key (KeystoreSetMethod). Get is OK.
• [x] LongLivedToken*tMethod should be rejected for delegates
• [x] JMAP Forward method: I think only the base user should be allowed to do this....
