tomnewton-mulga 69c8b20b78 fix: harden ISO installer error handling and safety checks ...

- partUUID: error on empty blkid output instead of writing UUID= to fstab
- installBootloader: fail if both EFI and BIOS targets fail; track efiErr
- machine-id fallback: write at mode 0600 so systemd can commit on first boot
- Run: defer unmount so partitions are always cleaned up on failure
- copyRootfs: verify critical paths exist after rsync before continuing
- resolveNIC: skip virtual/bridge interfaces (docker0, virbr0, ovs-system)
- EjectAndReboot: use syscall.Reboot instead of exec(reboot) which needs D-Bus
- ui.Run: return error on TTY open failure instead of silent fallback
- firstboot script: trap EXIT to always self-disable, preventing retry loops
- enableUnit/enableBannerUnit: deduplicate into enableSystemdUnit; check Remove
- runAdminBanner: promote service restart failure to slog.Error
- parseNodeConf: log non-ENOENT read failures
