Fix INSTALL.md inaccuracies

- Remove non-existent Proxmox LXC installer section (install.sh is actually
  the unified agent installer, not an LXC container creator)
- Fix Helm install command to use GitHub Pages repo instead of non-existent
  OCI registry
- Add proper systemd installation instructions with actual commands
- Remove non-existent CLI commands (pulse config rollback, pulse-update.timer)
- Add Kubernetes update/uninstall commands
- Add sudo where needed for systemd commands
