Add advanced Plex database recovery and restoration scripts
- Introduced `recover-plex-database.sh` for comprehensive database recovery with multiple strategies, logging, and rollback capabilities. - Added `restore-plex.sh` for safe restoration of Plex backups, including validation and dry-run options. - Created `plex-db-manager.sh` to consolidate database management functionalities, including integrity checks and service management. - Enhanced logging and error handling across all scripts for better user feedback and troubleshooting. - Implemented safety measures to prevent running scripts as root and ensure proper service management during operations.
