Improve database performance and SQL handling
- Introduced SQLite pragma tuning in the Database initialization for improved performance.
- Wrapped multiple database operations in transactions to optimize batch processing in MessageDAO.
- Updated DatabaseSchema to version 39, adding new indexes for better query performance.
- Improved test coverage for batch operations and SQL injection scenarios in the DAO layer.
