fix: migration dedup and legacy reconcile gaps

- Removed double log line in runMigrations (migration name printed twice)
- Added v0.54 (user_settings) and v0.55 (user_login_history device metadata) to reconcileLegacyMigrations
- Both are idempotent, no data was ever lost, but legacy upgrades were re-running them unnecessarily
