Method FCMClient

api/pkg/di/container.go:543–560

FCMClient creates the appropriate FCM client based on configuration. When FCM_ENDPOINT is set, it returns an EmulatorFCMClient that sends notifications directly to the phone emulator via HTTP. Otherwise, it returns a FirebaseFCMClient that uses the real Firebase SDK.
