HOMEPAGE_ALLOWED_HOSTS now carries the IP:port form; direct access to
http://10.0.50.45:5100/ returns 200 and the host-validation errors are gone
from the container log.
The .env was mode 644 holding the Plex and Jellyfin API keys; now 600. It is
root-owned, so editing it needs the infra-ops identity -- lkraven has only
password-sudo on that host.
Also records that Homepage renders client-side, so grepping the served HTML
to verify a config change is the wrong instrument (it gave a stale prerender
and then an empty page). GET /api/services is the honest check, and config
changes need a recreate rather than a restart.
