Unified push nextcloud notifications

[gavine99]

minimal changes to set the stage to allow the existing 3rd party nextcloud unified push app to send system notifications as push notifications to nextcloud mobile client and talk apps - https://apps.nextcloud.com/apps/uppush / https://codeberg.org/NextPush/uppush.

requires deployment sync with pull request for nextcloud server with same title - Unified push nextcloud notifications - nextcloud/server#47763

these pull requests are independent of, but will ultimately work with, a pull request for the unified push app to enable it to send push notifications to the nextcloud mobile client and talk apps - https://codeberg.org/NextPush/uppush/pulls/17

i have also submitted pr's for the generic (f-droid) android nextcloud client and talk apps to leverage the pr's above to create an end-to-end solution for unified push notifications and talk;

nextcloud mobile client app: nextcloud/android#13516
nextcloud mobile talk app: nextcloud/talk-android#4169

• this pr fails ci tests because it depends on the related notification app pr

I think you'd like to be always notified, not only when using the explicit delete?
But also e.g. when someone enters a Talk chat which marks all mention notifications read when they scroll down, Or when they join a call the call notification is removed.

This basically means you would want to be an NotificationApp yourself and listen to the markProcessed handling.

It's a bit weirdly abstracted and not clear (also not aware), but technically it is not required that the notifications app is not the only notification app. That's exactly why the API never operates based on IDs.
I guess you'd like to "be part of it" and basically want to act based on this app's notification id?
Similarly how we do it for the existing Push class:

notifications/lib/App.php

Lines 70 to 74 in 0b63d0e

	foreach ($deleted as $user => $notifications) {
	foreach ($notifications as $data) {
	$this->push->pushDeleteToDevice((string)$user, [$data['id']], $data['app']);
	}
	}

Best idea that comes to my mind would be to emit an event in this app here with all deleted IDs?
