Oracle DR: Fix backup retention and monitoring for new naming convention

Browse Source 
Problem: Backups accumulated on DR (73 files, 4 days) instead of keeping only 2 days
- transfer_incremental.ps1 had no cleanup function (ran 2x/day without cleanup)
- transfer_to_dr.ps1 cleanup had poor logging
- oracle-backup-monitor-proxmox.sh couldn't detect new L0/L1 backup format

Changes:
- Add cleanup to transfer_incremental.ps1 (delete backups older than 2 days)
- Improve cleanup logging in transfer_to_dr.ps1 (shows count before/after)
- Update oracle-backup-monitor-proxmox.sh to detect both naming conventions:
  * Old: *FULL*.BKP, *INCR*.BKP
  * New: L0_*.BKP (Level 0), L1_*.BKP (Level 1)
- Remove temporary files from /input/ directory

Result: Monitor now correctly reports backup age, cleanup runs after each transfer
