PR #258 External API (Number trivia), comment bugfix, more unit tests
Unit tests for HomeScreen.test.tsx and PostItem.test.tsx are in mobile/__tests__/ and were merged via issue #217 .
Researched suitable external APIs and selected the public Numbers API for its simplicity and fit with our existing totalUserCount variable.
Implemented a new backend route /api/number/{n} by adding three Java files:
NumberController.java to expose the endpoint
NumberService.java to call the Numbers API and handle fallbacks
NumberTriviaResponse.java to model the returned JSON
On the mobile side, extended HomeScreen so that immediately after fetching usersCount it calls /api/number/{usersCount} and saves the returned trivia text.
Updated the UI to render the trivia fact below the trending posts (see screenshot in commit).
All changes committed in 25c6333 on mobile-kerim branch and documented in issue #257 : backend service, controller, response model and mobile integration complete.
