Oracle DR: Fix verification commands and auto-start services

weekly-dr-test-proxmox.sh:
- Replace Unix commands (echo, grep) with PowerShell equivalents
- Use PowerShell Select-String for database status verification
- Fix table count query to work properly through SSH

rman_restore_from_zero.ps1:
- Set Oracle service to AUTOMATIC startup (was manual)
- Set Listener service to AUTOMATIC startup
- Auto-start Listener after database restore
- Add fallback to lsnrctl if service start fails
