revert the second server too: one officer, one token, this origin

Andre wants to log out and log back in against a single server, so this takes out dc6b623 and my
token-resolution change with it — the latter first, because it was written against
useServerClient, which dc6b623 introduced.

Gone: the connections store, the server chips, the per-server client and the per-server socket
url. `useClient()` is back to one origin, `/api`, and the session it already holds. The chat
socket url is back to what it was:

  const token = localStorage.getItem('BEARER_TOKEN');
  const wsUrl = `${protocol}//${window.location.host}/api/chat/ws?token=${token}`;

Verified: the staged tree is byte-identical to dc6b623^ across all of src/.

Two things he should know rather than discover.

The old line reads localStorage and nothing else — the same single spelling I widened an hour ago
and have now removed again. If his token is NOT in localStorage, this code fails exactly as
before, and worse: a missing one interpolates as the literal string "null" rather than an empty
value. Reverting cannot fix that class of problem; it restores it.

`officer.connections.v1` stays in his browser's localStorage with alpha's API key in it. Nothing
reads it now, so it is inert, but it is a credential sitting in a store nobody owns any more and
should be cleared by hand.

Typecheck clean. 600 pass, 2 fail — cliamp and pty, unchanged all evening and unrelated.
