⚡ Bolt: Optimize FlatList performance by memoizing handlers

[kourdroid]

💡 What: Wrapped renderIncidentItem, the inline onEndReached function (extracted to handleEndReached), and openIncidentDetails in useCallback in app/(tabs)/home.tsx. Created .jules/bolt.md to log this learning.
🎯 Why: React Native's FlatList component is highly sensitive to prop changes. Passing inline functions or unmemoized functions to props like renderItem or onEndReached causes those functions to be recreated on every render of the parent component. This forces every item in the list to re-render needlessly, which significantly degrades performance, causes stuttering during scrolling, and wastes CPU cycles, especially for long lists or complex list items.
📊 Impact: Prevents unnecessary re-renders of the incident list items when unrelated parent state changes (e.g., opening a modal). Improves list scrolling performance and general app responsiveness on the Home screen.
🔬 Measurement: Verify by observing smoother scrolling performance and reduced CPU/memory usage during list updates and pagination on the Home screen. The React DevTools profiler will show fewer unnecessary renders for list item components.
