Federation models (FederationConnection, FederatedIdentity,
FederationMessage) and their enums were defined in the Prisma schema
but never had CREATE TABLE migrations. This caused the
20260203_add_federation_event_subscriptions migration to fail with
"relation federation_messages does not exist".
Adds new migration 20260202200000 to create the 3 missing enums,
3 missing tables, all indexes, and foreign keys. Removes the
now-redundant ALTER TABLE from the 20260203 migration since
event_type is created with the table.
