 *
 * 收件者依 controller 原始碼確認：
 *   - BookingCreated      → $provider->notify()
 *   - BookingConfirmed    → $booking->member->notify()
 *   - BookingRejected     → $booking->member->notify()
 *   - BookingCancelled (member)   → $provider->notify()
 *   - BookingCancelled (provider) → $booking->member->notify()
