fix(deploy): split ingress to oolon, expose api on nikola interface

The per-site nginx ingress for rob.tn lives on oolon (the host the
external router forwards 443 traffic to), not on nikola. Adjust the
topology so:

- web (static ui + nginx) → oolon.hanzalova.internal
- api binds 0.0.0.0:42424 on nikola.kosherinata.internal so oolon
  can reverse-proxy across the WG mesh
- new firewalld service moments-api opens 42424 in the default zone
  on nikola
- oolon labels port 42424 http_port_t so httpd_t may name_connect
  outbound to it (httpd_can_network_connect was already set)
- nginx ssl_certificate switched to oolon's host cert; upstream
  rewritten to nikola.kosherinata.internal:42424

Plaintext between oolon and nikola for now — the WG mesh provides
the encryption layer and the data is already public. Documented
the deferral so a future move to per-hop mTLS is obvious.

<description>moments read-only HTTP API. Reverse-proxied by nginx on oolon (the per-site rob.tn ingress) across the WG mesh; the data is the public timeline already exposed at rob.tn, so no source-IP restriction is currently applied. Add a &lt;source/&gt; element here if defence-in-depth scoping to oolon's WG IP becomes desirable.</description>

Postgres roles `moments_rw` and `moments_ro` must exist on the primary, with `pg_ident.conf` mappings in place for `nikola.kosherinata.internal``moments_ro` and `frootmig.kosherinata.internal``moments_rw`. See `asset/sql/bootstrap-moments.sql` and `asset/postgres/ident.conf.tmpl`.
Inter-host traffic over the WG mesh: oolon's nginx connects to `http://nikola.kosherinata.internal:42424` in plaintext. The mesh provides the encryption layer; per-hop TLS for an internal HTTP read-only API on already-public data is deferred. If that changes, swap the api binary to rustls + the host cert pair, and update the nginx upstream to `https://`.
Secrets resolved by `deploy.sh` via `pass`:
