Fix \!backup command not working - module loading issue

Fixed BackupCommands module not being loaded into the bot system:
- Added BackupCommands to modules/__init__.py imports and __all__ list
- Added BackupCommands to module loading in run_bot_with_reconnect.py
- Fixed constructor signature to match BaseModule requirements

All 5 backup commands now properly registered and available to admin users:
- \!backup - Create manual database backups
- \!restore - Restore from backup files
- \!backups - List available backups
- \!backup_stats - Show backup system statistics
- \!backup_cleanup - Clean up old backups based on retention policy
