Add integration test for notification delivery and simplify test helpers

- Add comprehensive integration test covering card assignment, comments,
  mentions, email bundling, and edge cases (system user, inactive user)
- Inline push notification test helpers into the only test that uses them
- Remove separate PushNotificationTestHelper module
