Complete fix: Replace all sudo commands with su for LXC compatibility

- Replace 'sudo -u' with 'su -' throughout the script
- Works perfectly in LXC containers running as root (no sudo installed)
- Also works on regular VMs/servers where sudo is available
- Fixes all remaining: sudo: command not found errors
