Refactor variable assignments and improve script readability in validate-plex-backups.sh and validate-plex-recovery.sh
- Changed inline variable assignments to separate declaration and assignment for clarity. - Updated condition checks and log messages for better readability and consistency. - Added a backup of validate-plex-recovery.sh for safety. - Introduced a new script run-docker-tests.sh for testing setup in Docker containers. - Enhanced ssh-login.sh to improve condition checks and logging functionality.
