Reads the per-server Officer Companion (COMMS/HEADSCALE_COMPANION_API.md): container health with its
own diagnosis, a log snapshot, a live SSE tail, and restart/stop/start.
The companion sits at ${server.url}/officer-api behind the same admin key we already store, so there
is nothing new to register — but only the sidecar can decrypt that key, so the sidecar proxies it and
the browser never talks to the companion directly. That also rules out EventSource for the stream
(no Authorization header), which is why the tail is fetch() + a hand-rolled SSE reader.
Two inversions the code is built around: /health is always HTTP 200 and must be read by verdict, and
an absent companion is a state to render rather than an error — an HTML 502 is nginx, a JSON 502 is
the companion reporting a failed docker op, and the admin API on the same domain is independent
either way.
