fix: Resolve database migration issues and consolidate 003 migrations

- Fix $getActiveIdentity() logic flow preventing false "empty table" warnings
- Implement auto-selection of first account when activeDid is null after migration
- Consolidate 003 and 003b migrations into single 003 migration
- Re-introduce foreign key constraint for activeDid referential integrity
- Add comprehensive debug logging for migration troubleshooting
- Remove 003b validation logic and update migration name mapping

Fixes migration from master to active_did_redux branch and ensures system
always has valid activeDid for proper functionality.
