feat(migration): complete Step 1 of ActiveDid migration - update () to use new API

- Update () to call () with fallback to settings
- Maintain backward compatibility while using new active_identity table
- Update migration plan documentation to reflect completed Step 1
- Restore Playwright workers to 4 (was accidentally set to 1)

Tests: 39/40 passing (1 unrelated UI failure)
Migration progress: Step 1 complete, ready for Step 2 dual-write implementation
