Fix worker-only database architecture and Vue Proxy serialization

- Implement worker-only database access to eliminate double migrations
- Add parameter serialization in usePlatformService to prevent Capacitor "object could not be cloned" errors
- Fix infinite logging loop with circuit breaker in databaseUtil
- Use dynamic imports in WebPlatformService to prevent worker thread errors
- Add higher-level database methods (getContacts, getSettings) to composable
- Eliminate Vue Proxy objects through JSON serialization and Object.freeze protection

Resolves Proxy(Array) serialization failures and worker context conflicts across Web/Capacitor/Electron platforms.
