Add comprehensive Acronis backup management interface

Implemented complete backup management section with acrocmd integration:

New Features:
- Backup Manager: Centralized interface with organized sections
  • Agent Management (status, logs)
  • Backup Operations (list, trigger, status)
  • Plan Management (view, manage protection plans)
  • Restore Operations (placeholder for future)

Scripts Created:
- acronis-backup-manager.sh: Main backup management menu
- acronis-list-backups.sh: Lists archives and backup details
- acronis-trigger-backup.sh: Triggers manual backups with plan selection
- acronis-backup-status.sh: Shows active tasks and recent activities
- acronis-schedule-viewer.sh: Displays protection plans and schedules
- acronis-plan-manager.sh: Manages protection plans (view/enable/disable/delete)

Integration:
- All scripts use acrocmd CLI for programmatic backup operations
- Updated Acronis menu with streamlined "Manage Backups" option
- Reorganized menu structure for better usability
- Added proper error handling and status checks
