Implement zap notification support for push notifications
The code paths for generating zap notifications were very different from the paths used by most other notifications. In this commit, I include the logic and data structures necessary for formatting zap notifications in the same fashion as local notifications. A good amount of refactoring and moving functions/structures around was necessary to reuse zap local notification logic. I also attempted to make the notification generation process more consistent between zaps and other notifications, without changing too much of existing logic to avoid even more regression risk. General push notifications + local notifications test ----------------------------------------------------- PASS Device: iPhone 15 Pro simulator iOS: 17.0.1 Damus: This commit Setup: - Two phones running Damus on different accounts - Local relay with strfry-push-notify test setup - Apple push notification test tool Coverage: 1. Mention notifications 2. DM notifications 3. Reaction notifications 4. Repost notifications Steps for each notification type: 1. Trigger a notification (local and then push) 2. Ensure that the notification is received on the other device 3. Ensure that the notification is formatted correctly 4. Ensure that DMs are decrypted correctly 5. Ensure that profile names are unfurled correctly 6. Click on the notification and ensure that the app opens to the correct screen Result: PASS (all notifications received and formatted correctly) Notes: - For some reason my relay is not receiving zap events, so I could not test zap notifications yet. - Reply notifications do not seem to be implemented yet - These apply to the tests below as well Changelog-Added: Zap notification support for push notifications Signed-off-by: Daniel D’Aquino <daniel@daquino.me> Signed-off-by: William Casarin <jb55@jb55.com>
