Add hashed valherun password to bootstrap

 The wrapper script is [`scripts/post-install-bootstrap.sh`](/usr/local/valherun/pxe_boot_alma/scripts/post-install-bootstrap.sh). It clones those repos onto the installed Alma host and then runs the reusable pieces directly:

-The `valherun` step is handled locally in this repo instead of calling `kickstart/bin/create_valherun.sh` because that upstream helper runs `passwd valherun`, which blocks unattended Kickstart `%post`. The SSH helpers are run with `--no-reload` so the install does not depend on reloading `sshd` inside the installer chroot.
+The `valherun` step is handled locally in this repo instead of calling `kickstart/bin/create_valherun.sh` because that upstream helper runs `passwd valherun`, which blocks unattended Kickstart `%post`.

 The PXE bootstrap also pins the preferred `codex` public key directly in [`scripts/post-install-bootstrap.sh`](/usr/local/valherun/pxe_boot_alma/scripts/post-install-bootstrap.sh) so unattended installs do not inherit the fallback key embedded in the shared `tools` helper.
