[ML 0.7/LL.03] - UI Integration & Refresh

🎯 The objective

Connect the MessageListFragment and ViewModel to the new data loading mechanisms. This brings the feature to the user by enabling infinite scrolling (lazy loading) and updating the pull-to-refresh logic.

🎒 Resources

ℹ️ List all relevant resources like BugZilla meta bugs, Figma files, Notion links and other files. These can be filled in later.

🦮 Rules of the Road

🟢 In Scope

• Trigger infinite loading events when the user scrolls near the end.
• Migrate pull-to-refresh logic to use the RemoteMediator.

🔴 Out of Scope

• Changes to the Visual Design of the list items (unless loading indicators require it).

🚧 Technical and/or Business Requirements

• Lazy Loading:
  • The fragment must trigger a load event before the user hits the absolute bottom.
  • Delegate data retrieval to the Remote Mediator via the VM.
  • Design Requirement: May need a design iteration for the "Loading more data" indicator.
• Pull-to-refresh:
  • Must propagate the refresh request to the VM -> Remote Mediator to fetch new data from remote specifically.
