Auto-dismiss push notifications when email is read on another device

Currently, when I receive a push notification on my iOS device about a new email, the notification remains visible even after I've opened and read that email on another device (such as my laptop or desktop). This creates notification clutter and doesn't reflect the actual state of my inbox.

Proposed Feature:
Implement cross-device notification synchronization so that push notifications are automatically dismissed on iOS when the corresponding email is read on any other logged-in device.

Use Case:
Receive email notification on iPhone
Open and read the email on laptop/desktop
Notification automatically disappears from iPhone lock screen and notification center

Benefits:
Reduces notification clutter
Provides accurate inbox state across all devices
Improves user experience by eliminating manual notification dismissal
Brings Proton Mail in line with other modern email clients that support this feature
