New global push/ module mirroring mail/ and files/storage/:
- PushProvider abstraction; default LogPushProvider (no delivery, logs),
PUSH_PROVIDER=fcm switches to FcmPushProvider — Firebase Cloud Messaging
HTTP v1, authenticated by a service-account JWT exchanged for an OAuth
token (no extra dependency; jsonwebtoken does the signing). Prunes tokens
FCM reports as invalid.
- DeviceToken model (token + platform, bound to a User or GuestAccount),
migration + added to the sync log.
- POST /api/push/register + /unregister (any of the three token kinds).
- PushService.notifyChannel() resolves a channel's readable audience
(DIREKT participants / LT / Gemeinde members + guests / whole KC for
broadcast), looks up their device tokens (minus the sender), sends.
- ChatService.sendMessage() fires it best-effort after persisting.
New env: PUSH_PROVIDER, FCM_PROJECT_ID (default konfi-castle-app),
GOOGLE_APPLICATION_CREDENTIALS.
Verified against local Postgres: register a token, send a Gemeinde-group
chat message from another member -> log-push logs "would push ... to 1
device". Real FCM send needs the service-account JSON. npm test 56.
