Oracle DR: Phase 6.5 - Complete cleanup and restore scripts (TESTING)

Browse Source 
Major improvements to DR restore workflow:

**New Scripts:**
- cleanup_database.cmd: Complete cleanup using oradim + registry deletion
- rman_restore_from_zero.cmd: Copy backups to recovery_area + restore

**Key Solutions Implemented:**
1. RMAN AUTOBACKUP limitation: Must have backups in recovery_area
   - Solution: Copy ALL backups from F:\ (NFS) to C:\...\recovery_area
   - Performance: 6.7 GB copied in ~2 minutes

2. Oracle service persistence issue: Service remains after sc delete
   - Solution: Use oradim -delete -sid ROA (proper Oracle cleanup)
   - Bonus: Delete registry keys to ensure clean state

**Current Status:**
- Cleanup: ✅ TESTED (oradim works perfectly)
- Backup copy: ✅ TESTED (6.7 GB in 2 min)
- RMAN restore: 🟡 IN PROGRESS (expected completion 03:35-03:40)

**Updated:**
- DR_UPGRADE_TO_CUMULATIVE_PLAN.md: Progress tracking + solutions documented
- rman_restore_final.cmd: Use F:\ mount point
