MechaCat02 77d55e941c harden(deploy): add app/frontend healthchecks + readiness-gate Caddy
Caddy depended on app/frontend with no readiness gate, so it could proxy to a
not-yet-listening upstream and surface brief 502s on boot/restart. Add
wget-based healthchecks (busybox wget ships in both alpine runtime images):
app hits the unauthenticated /health, frontend hits / (SSR returns 200; the
redirect is client-side). app uses a 30s start_period to cover boot-time
migrations. Caddy now depends_on both with condition: service_healthy.
