fix: maintain separate master/account settings in SQLite migration

- Update settings migration to maintain separate master and account records
- Use activeDid/accountDid pattern to differentiate between settings types:
  * Master settings: activeDid set, accountDid empty
  * Account settings: accountDid set, activeDid empty
- Add detailed logging for settings migration process
- Focus on migrating key fields: firstName, isRegistered, profileImageUrl,
  showShortcutBvc, and searchBoxes
- Fix issue where settings were being incorrectly merged into a single record

This change ensures the SQLite database maintains the same settings structure
as Dexie, which is required by the existing codebase.
