fix: network-first boot order, OVMF dispatch chain working

- Kickstart %post now restores network-first EFI boot order (undoes
  Anaconda's disk-first default). Grep pattern includes HTTP boot entries.
- Test force-restarts VM after install so OVMF rereads NVRAM.
- VM successfully network-boots after install, hits /dispatch, bastion
  returns exit (local boot). Confirmed in test logs.
- nofail on /boot/efi fstab entry prevents emergency mode.
- Remaining: Fedora disk boot after iPXE exit may still fail.
