Records the decision #177 asked for, the other way round: the hypervisor has no
inbound path and the labs Caddy already holds 80/443 and the wildcard cert, so
the portals go through it over a reverse SSH tunnel instead of an in-cluster
edge. Covers keycloakUrl, KC_PROXY_HEADERS and the optional demo OTP autofill.
