FCM Configuration for DNZ Notifications
FCM is used for native Android and Firebase-oriented delivery paths. It complements Web Push instead of replacing it for browser users.

Credential model
Upload or configure the FCM credentials for the workspace in the mobile push area. Treat service account material as secret and never ship it to a mobile app.
The app registers a device token or connection data with the backend. The backend stores it under the recipient and routes future push messages to the available transport.
