Fix InviteOneAcceptView migration fence; remove USE_DEXIE_DB dependency

- Remove USE_DEXIE_DB import from app.ts constants
- Update InviteOneAcceptView to use PlatformServiceMixin pattern
- Remove legacy Dexie database access code
- Move WORKER_ONLY_DATABASE_IMPLEMENTATION.md to doc/ directory
- Remerge changes in router/index.ts

Fixes Electron build failure caused by missing USE_DEXIE_DB export.
