/api/readyz is a public monitoring endpoint like /api/health.
app.basePath("/api") + api.use("*", authMiddleware) applies to all
/api/* paths regardless of route registration order (GRO-2692 UAT
failure: Hono basePath middleware bypass).

/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).
CTO architectural ruling (PR #235 review): K8s readiness/liveness probes
must remain DB-less to prevent transient DB blips from cycling pods. The
/api/readyz endpoint (GRO-2687) is the canonical DB-health signal for the
monitoring layer and satisfies the GRO-2678 detection-gap requirement.
Removes:
- GET /health/ready route from src/index.ts
- src/__tests__/health-ready.test.ts
