- flake.nix: add nodejs_22, firebase-tools, and google-cloud-sdk to the dev
shell so the relay can be tested, built, deployed, and administered locally
- backend settings: point default_relay_url at the deployed relay
- rename the relay liveness route /healthz -> /health: Google Front End
reserves /healthz and returns its own 404 before the request reaches Cloud
Run, so the probe was unreachable (verified live; /v1/push and the FCM path
work end-to-end)

- Drop all private data from push payloads: send only the already-sanitized
title/body, no data field, no MAC/IP, and no deep-link (tap just opens the app)
- Correct backend integration points: sender at src/notifications/push.rs and a
"push" arm in deliver() (not events.rs); add module registrations and an HTTP
client (reqwest) dependency
- Unify nomenclature on "push": method value "push", relay under push_relay/,
config section [notifications.push], sender module push.rs
