feat(db)!: complete ActiveDid migration to active_identity table

Migrate all 34 Vue components from settings.activeDid to $getActiveIdentity()
pattern. This completes the database architecture improvement that separates
identity selection from user preferences and prevents data corruption.

- Replace this.activeDid = settings.activeDid with $getActiveIdentity() calls
- Add ESLint ignore comments for TypeScript type assertions
- Update migration plan documentation to reflect completion
- All components tested with passing results

BREAKING CHANGE: Components now use active_identity table as single source
of truth for activeDid values instead of settings table
