Migrate FCM from legacy v1 API to HTTP v2 with service account auth

Replace deprecated FCM server key authentication with Google service
account OAuth2 flow. The class now creates a signed JWT from the
service account credentials, exchanges it for a short-lived access
token (cached via WordPress transients), and sends messages to the
FCM v2 endpoint (projects/{id}/messages:send).

Settings page updated: FCM Server Key field replaced with Firebase
Project ID + Service Account JSON textarea with validation.
