Implement dynamic database path configuration in database.js, enhancing compatibility with Docker and local development environments. Update db.js to log the database connection path. Remove response data truncation in validator.js for improved readability.

- Integrated a logging service to redirect console outputs.
- Added new endpoints for managing logs:
  - Retrieve log file list
  - Read specific log file content
  - Fetch recent logs
  - Stream logs via Server-Sent Events
  - Search logs by keyword
  - Cleanup old log files
- Updated application metadata to include new log management features.
