fix(GRO-1566): bypass auth for /api/health endpoint on UAT

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.
