WIP: Oracle DR CUMULATIVE backup upgrade - Phases 1-3 completed

COMPLETED:
- Phase 1: Proxmox host storage (/mnt/pve/oracle-backups/ROA/autobackup)
- Phase 2: RMAN script already has CUMULATIVE keyword
- Phase 3: Transfer scripts updated for Proxmox host
  * transfer_incremental.ps1: 10.0.20.37:22122 → 10.0.20.202:22
  * transfer_to_dr.ps1: Same change
  * Converted Windows PowerShell to Linux bash commands
- VM 109 cleanup: ~6.4 GB freed, RMAN catalog cleaned

NEW FILES:
- copy_existing_key_to_proxmox.ps1: Setup script for SSH key
- setup_ssh_keys_for_proxmox.ps1: Alternative setup (not used)

PENDING (Next Session):
- Run copy_existing_key_to_proxmox.ps1 on PRIMARY as Administrator
- Phase 4: Modify scheduled tasks (13:00 + 18:00)
- Phase 5: Configure mount point on VM 109 (F:\ drive)
- Phase 6: Update restore script for F:\ mount
- Phase 7: Test FULL + CUMULATIVE backup and restore

DOCUMENTATION:
- DR_UPGRADE_TO_CUMULATIVE_PLAN.md: Added implementation status
