Oracle DR: Add TestMode parameter for dual behavior

rman_restore_from_zero.ps1:
- Add -TestMode switch parameter
- TestMode (weekly DR test): Skip service/listener config, only verify restore works
- Standalone mode: Full config with SPFILE + Listener for production use

weekly-dr-test-proxmox.sh:
- Call restore script with -TestMode flag
- Avoids service recreation and SSH disconnect during tests

Benefits:
- Weekly tests are faster and cleaner (no service restart)
- Manual restore prepares system for production use
- No more 'Broken pipe' errors during tests
