🧪 [Add tests for short date formatter]

[TargetMisser]

🎯 What: The testing gap addressed
This PR addresses the lack of automated testing for src/utils/dateFormat.ts, specifically focusing on fmtDateShort, fmtTime, fmtOffset, and the MONTHS_IT array. A robust suite of unit tests has been introduced to ensure correct and expected behavior for these utility functions.

📊 Coverage: What scenarios are now tested
The new tests cover:

• Standard date formatting and correctness for fmtDateShort
• Proper leap year handling for 2024-02-29
• Year bounds considerations (2000 vs 2100 leap year rules)
• Invalid date strings gracefully avoiding crashes
• Time strings formatted with correct padding from seconds/milliseconds offsets (fmtTime, fmtOffset)
• Verifying the Italian months mapping MONTHS_IT contains correct 12 elements.

✨ Result: The improvement in test coverage
The module src/utils/dateFormat.ts is now covered by automated tests, adding confidence during future refactoring and improving overall reliability. Additionally, the groundwork for testing using Jest and jest-expo is correctly configured for any upcoming Expo/React Native-dependent testing.
