feat(webui): signed-in read-only Console preview behind the edge proxy (#1568, row 74)

Browse Source 
serve takes --public-host NAME --auth-header HEADER --allow-user ID, all
three or none. With them, a request whose Host is NAME must carry HEADER
equal to ID or gets 403; a request that carries HEADER with any other Host
gets 403, so a proxy that rewrites Host can't reach the loopback path with
a signed-in request; every POST is refused read-only. A repeated Host gets
400 in both modes. Host and header names compare case-insensitively
(Traefik sends X-Authentik-Uid). The README states the proxy contract:
the edge forwards Host unchanged and strips client copies of HEADER.

Author: Dewey. Round 2 candidate manifest
17b6d7f62d106a23d99441eefa46e34ab2e9bd1442a1d02e219f126a82a8668d (base
17ea0dbc, no drift on the 4 paths through 60c8dcf9). Approved by Filbert
(comment 27485) and Darkwing (comment 27486) on #1568. Their wording
notes on the README (first signed-in request; the tunnel sentence) go to
row 76, which owns the README next.

Sage gate rerun on a worktree of a55915f0 with the patch: manifest OK;
webui 61/61, control-board 124/124, cli 113/113; test-auth 15, conductor
17, config 24, extension-package 18, foundation 44, queue 27, release 14,
task 98, all 0 failed. test-discord failed one timing test (engine: a
timed-out run outlives the grace, 280 ms at load 30) on the sequential
run and passed 66/66 on a solo rerun of the same worktree; the patch
touches no discord file.
