Improve open action handling for notifications

Browse Source 
Push notifications were not opened reliably. To improve robustness, the
following changes were introduced:
1. The notification opening logic was updated to become more similar to
   URL handling, in a way that uses better defined interfaces and
   functions that provide better result guarantees, by separating
   complex handling logic, and the side-effects/mutations that
   are made after computing the open action — instead of relying on a
   complex logic function that produces side-effects as a result, which
   obfuscates the actual behavior of the function.
2. The LoadableThreadView was expanded and renamed to
   LoadableNostrEventView, to reflect that it can also handle non-thread
   nostr events, such as DMs, which is a necessity for handling push
   notifications.
3. A new type of Notify object, the `QueueableNotify` was introduced, to
   address issues where the listener/handler is not instantiated at the
   time the app notifies that there is a push notification to be opened.
   This was implemented using async streams, which simplifies the usage
   of this down to a simple "for-in" loop.
