test(auth): lock in POST logout from gateway-offline banner (#3001) (#4506)
* test(auth): lock gateway-unavailable logout to POST (#3001)

Issue #3001 reports that the gateway-unavailable fallback rendered the
recovery action as a plain link to /api/v1/auth/logout, which browsers
navigate via GET against a POST-only endpoint — returning 405 and
leaving the stale session cookie intact while the gateway is down or
restarting.

The code-level fix already landed in #3495: <GatewayOfflineBanner>
renders a <button onClick={logout}> wired to AuthProvider.logout's
fetch(..., { method: "POST" }). That PR's test suite, however, only
covers the banner's pure helpers (visibility + retry interval) and the
gateway_unavailable SSR tag — it never asserts that the recovery action
actually reaches the network as a POST, so a regression back to a
GET-style link/navigation would slip through silently.

Add a DOM-level regression test that renders the banner inside a real
AuthProvider, simulates a still-down gateway for the /auth/me probe (so
the banner stays mounted and its recovery button stays actionable),
clicks the button, and asserts that the resulting request is
POST /api/v1/auth/logout — never GET. This pins the exact behaviour
#3001 requires and fails loudly if the affordance ever regresses.

Closes #3001.

* test(auth): guard logoutCall against undefined in gateway-offline-banner test

TypeScript's noUncheckedIndexedAccess types logoutCalls[0] as T|undefined,
which surfaced as TS18048 on the three logoutCall.{url,method} accesses.
The waitFor callback already asserts toHaveLength(1) before returning; add
an explicit throw guard so the value narrows to a defined Call and the
assertions below type-check.

Unblocks lint-frontend on #4506.
