Adds a deliberate extra sign-in layer covering the entire nginx gateway
(portal page + every proxied web UI) via a shared htpasswd credential
generated on the FreeIPA container and published to nginx through a new
portal-auth volume. FreeIPA, CheckMK and Keycloak still each enforce their
own login behind it — two prompts beats one attacker who only had to beat
one lock. Healthcheck updated to treat 401 as healthy accordingly.

Add an nginx service that fronts all three web UIs on a single hostname/port
and serves a portal landing page, designed to sit behind the operator's own
TLS-terminating reverse proxy.
- Each backend is proxied at the path it already serves natively — FreeIPA
/ipa, CheckMK /cmk, Keycloak under a configured /auth relative path — so no
fragile path rewriting is needed and one upstream proxy line exposes
everything. FreeIPA's strict Host/Referer anti-CSRF checks are satisfied by
pinning Host to the IPA hostname and rewriting Referer.
- Honors incoming X-Forwarded-Proto/For so it works behind a second reverse
proxy (double-proxy verified: portal, FreeIPA, CheckMK and Keycloak all
reachable through two layers, and a CheckMK login POST completes to an
authenticated session through the gateway).
- Keycloak: KC_HTTP_RELATIVE_PATH=/auth + KC_PROXY_HEADERS=xforwarded so it
builds correct URLs behind the gateway; deliberately not forwarding
X-Forwarded-Port (this gateway is :80 internally; the public port is the
upstream proxy's) to avoid https://host:80 redirects.
- .env.example documents ANSIPA_HTTP_PORT and gives the exact upstream
reverse-proxy snippet (nginx location block + Caddy one-liner).
Portal is a static cyberqueer-themed page linking to /ipa/ui/, /cmk/, /auth/.
