Remove unused Trie and UserSearchCache as they have been superseded by NostrDB

Changing the notification mode setting requires successfully sending or
revoking the device token to the server. As this is an action that might
fail, it is important to have a clear UX feedback in case this fails.

Damus: This commit
strfry-push-notify: d6c2ff289c80e0a90874a7499ed6408394659fc9
Coverage:
1. Checked that push notification mode setting is invisible when experimental push notifications mode is disabled
2. Checked that push notification mode setting is visible when experimental push notifications mode is enabled
3. Checked that switching between push and local notifications sends requests to the server
4. Checked that switching to push notification mode will cause local notifications to be suppressed and push notifications will be sent to the APNS server
5. Checked that switching back to local notification mode will cause local notifications to be displayed, and push notifications will NOT be sent to APNS
6. Checked that if the API server is off, switching from local to push notification modes is not possible and shows an error to the user.
7. Checked that sending APNS payload to Apple's test APNS page will actually deliver the push notification successfully.
