[Story] Silent unexpected notifications

[manuroe]

As a user, I do not want to receive technical notifications.

The server cannot evaluate push rules on E2E encrypted messages. The push rules can be evaluated only on device after decryption. This means that some pushes sent by the backend should be ignored and not turned into notifications displayed on the user's device.

Acceptance criteria

• If the pushed event doesn't match a push rule, we must not display a notification
• If the pushed event matches a push rule, we must display a notification containing the message content (nominal use case)
• If an error occurs during the push handling (network error, timeout, UTD, etc), we must display the default Notification as a notification so that the user can open the app and checks what is happening. They will not miss important messages.
• If the pushed event matches a push rule but the app is not able to render it, we must display the default Notification as a notification
