Select calendar specific notifications

Is your feature request related to a problem? Please describe.

Instead of activating a "global" notification for "A Deck{whatever} was edited" it would be really helpful to be able to select specific Boards/Lists that I want to be notified on, instead of getting noise from all Boards and Lists.

This is of course also applicable for other things, for us especially for calendars.

I want to be notified of changes in deck/calendar X, but I can only turn on notifications for all deck/calendars, that are shared with me, which makes a lot of unnecessary noise.

Describe the solution you'd like
Select single Deck Boards/Lists to be notified of.

Additional context

I am not sure, whether "resources" is the right term for what I mean, excuse me if not.
If not so, the name of the issue is probably misleading, feel free to change as necessary.

This was opened https://github.com/nextcloud/notifications/issues/2705, but got referred to the apps themselves. I also opened this in calendar

Start by reviewing the linked notifications issue and calendar issue, then trace how Deck currently exposes global notifications for shared decks, boards, lists, or calendars. Done means users can select individual resources for notifications without receiving unrelated global changes, with the scope aligned across the affected apps.
