Update version to 8.1.3 and enhance database configuration for Synology NAS support

- Bumped version number in version.txt to 8.1.3.
- Added detection for Synology NAS in database.py to apply performance optimizations.
- Implemented specific database settings for Synology, including adjusted synchronous mode, cache size, and memory mapping.
- Enhanced logging to monitor optimization status for Synology configurations.
