playbooks: repoint the four remaining live fv-ml1 targets

homepage-regroup, mog-sec-move-to-gpu0, pull-hf-repo and serve-qwen3.5-122b
all carried runnable 'scripts/elway ana-ml2 --playbook ...' instructions or
the old 10.250.50.54 address. Each would fail today against a dead name and a
dead IP, so these are corrections rather than cosmetics. homepage-regroup is
renamed to match; the other three keep their names, which never carried the
host.
