v1.0.1 - Bugfix: Prevent Infinite Backup Loops

🐛 Bug Fixes

• Infinite Backup Loop Prevention: Fixed a critical bug where an unconfigured mailer (SMTP) would throw an uncaught exception during success/failure notifications. This prevented the next_run_at timestamp from updating and caused the scheduler to trigger the same backup job every minute. Mail notifications are now gracefully handled via try-catch blocks to ensure job state remains consistent even if email delivery fails.
