- Added ref="userNameDialog" to UserNameDialog in AccountViewView.vue template
- Patched onEditName() to check for dialog ref and open() method before calling
- Improved error notification to use NotificationIface fields (group, type, title, text)
- Prevents "Cannot read properties of undefined (reading 'open')" error if dialog is missing
- Removed all vestigial Dexie/USE_DEXIE_DB references from code and docs
- Centralized DB logic in PlatformServiceMixin; resolved logger/databaseUtil circular dependency
- Modularized SQL helpers (`$generateInsertStatement`, `$generateUpdateStatement`) and added unit tests
- Created/updated migration tracking docs and helper script for cross-machine progress
- Confirmed all lint/type checks and tests pass; ready for systematic file migration
