Add database schema, encryption utilities, and local database service
- Implement `schema.ts` for SQLite schema creation, indexing, and sync metadata initialization. - Develop `encryption.ts` with AES-256-GCM encryption utilities for securing database data. - Add `database.service.ts` to manage CRUD operations with encryption support, user-specific databases, and schema initialization. - Integrate book, chapter, and character operations with encrypted content handling and sync preparation.
