fix(schema): fix migration ordering hazard and FK guard for table rebuild

Browse Source 
Remove federated_id from addMissingColumns so it no longer races with
migrateDmChannelsFederatedId on installs that have canonical_pair_id.
Wrap the table rebuild in PRAGMA foreign_keys = OFF/ON with a transaction
so the DROP TABLE succeeds even when dm_members/dm_messages hold FK refs.
