Oracle DR: Complete Windows VM implementation and cleanup

Major changes:
- Implemented Windows VM 109 as DR target (replaces Linux LXC)
- Tested RMAN restore successfully (12-15 min RTO, 24h RPO)
- Added comprehensive DR documentation:
  * DR_WINDOWS_VM_STATUS_2025-10-09.md - Current implementation status
  * DR_UPGRADE_TO_CUMULATIVE_PLAN.md - Plan for cumulative incremental backups
  * DR_VM_MIGRATION_GUIDE.md - Guide for VM migration between Proxmox nodes
- Updated DR_WINDOWS_VM_IMPLEMENTATION_PLAN.md with completed phases

New scripts:
- add_system_key_dr.ps1 - SSH key setup for automated transfers
- configure_listener_dr.ps1 - Oracle Listener configuration
- fix_ssh_via_service.ps1 - SSH authentication fix
- rman_restore_final.cmd - Working RMAN restore script (tested)
- transfer_to_dr.ps1 - FULL backup transfer (renamed from 02_*)
- transfer_incremental.ps1 - Incremental backup transfer (renamed from 02b_*)

Cleanup:
- Removed 19 obsolete scripts for Linux LXC DR
- Removed 8 outdated documentation files
- Organized project structure
