/api/readyz was returning 401 Unauthorized in UAT (GRO-2692 Shedward
regression). The authMiddleware for /api/* did not whitelist /api/readyz,
causing every unauthenticated probe request to be rejected.
Add /api/readyz to the bypass condition alongside /api/auth/* and
/api/health. Add readyz-auth-bypass.test.ts confirming the route passes
through the middleware without auth and that non-whitelisted paths still
block (503 when auth not configured).
Closes GRO-2692 regression (UAT fail).
The /api/health endpoint returns 401 on UAT because authMiddleware
was not skipping it — the health check was registered on the Hono app
instance (not the api sub-router), placing it below authMiddleware on
the base app. The fix adds /api/health to the auth skip list alongside
/api/auth/.
The /health endpoint (registered at app level, above all middleware)
correctly returns 200. The /api/health endpoint must also be public
since the task requires confirming it returns 200.
