Every 400, 403, 404 and 500 on an admin page now answers with an
error page in the normal layout: one fixed line for the status and a
link back to the webhook list, or to sign-in when nobody is signed
in. The router's handler for unknown paths, the CSRF middleware's
refusal and a panic in an admin page route group use the same page;
each such group has its own recoverer and error reporting for that.
The page always sends Cache-Control: no-store. Status codes are
unchanged. The receiver, the healthcheck and /metrics keep their
plain answers. If the error page cannot render, or panics, the answer
is the same status in plain text.
Model: opus-5-5
Unifies user-visible copy on "Webhook" (routes and URLs unchanged), drops
the placeholder Profile settings section, and adds a copy-to-clipboard
affordance for the entrypoint URL as progressive enhancement — the button
stays hidden unless both the target element and the Clipboard API resolve,
so no dead control appears without JavaScript and the URL stays selectable.
Retention copy now matches what the code does: deletion is permanent, 0
retains forever, and a blank field means the default on create or the
current value on edit. The permanent-deletion sentence is suppressed for a
retain-forever webhook, which the reaper exempts before computing a cutoff.
Template tests gained a render-completed assertion. Without it, a page that
aborted mid-render still satisfied assertions matching the already-flushed
prefix, because renderTemplate streams to the ResponseWriter (#123).
