Refactor profile key extraction

When filling or updating a V2 group, profile keys were copied from
DecryptedGroup.members into the local profile store but not from
requestingMembers. Admins who never had a prior session with a user in
the join queue then lacked profile keys and could not decrypt profiles
(e.g. for listContacts).

Also process DecryptedRequestingMember entries the same way as full
members, using DecryptedMember / DecryptedRequestingMember types so the
lib module does not require a direct protobuf dependency.
