Account Notifications

Each user controls which events trigger notifications and which channels deliver them. Settings live under /app/notification-preferences.

Endpoints

GET /api/v1/notification-preferences      fetch current prefs
PUT /api/v1/notification-preferences      update

{
  uid: ObjectId,
  channel: "in_app" | "email" | "push",
  type: string,                       // event type
  enabled: boolean,
}

A preference is a tuple of (user, channel, type) — switching it off mutes that one combination.
