CRITICAL FIXES:
- Add check for successCount == 0 to properly fail when no databases restored
- Fix tryRestartPostgreSQL to use non-interactive sudo (-n flag)
- Add 10-second timeout per restart attempt to prevent blocking
- Try pg_ctl directly for postgres user (no sudo needed)
- Set stdin to nil to prevent sudo from waiting for password input
This fixes the issue where cluster restore showed success but no databases
were actually restored due to sudo blocking on password prompts.
