Prevent recurring infinite restart loop (389x crash) caused by drizzle
re-applying already-applied migrations when public.__drizzle_migrations
tracking is empty/partial.
- 0017/0018: ADD COLUMN IF NOT EXISTS (re-run safe)
- 0019: DO-block rename that handles all prior states (server_name-only,
both columns, or server_nick-only) so it never errors or double-renames
- seedDrizzleHistory: reconcile tracked created_at to the journal's latest
'when' when the schema already reflects the latest migration, instead of
early-returning on an existing-but-empty/partial tracking table
