⚡ Bolt: Add FlatList virtualization to improve performance

[TargetMisser]

💡 What:
Added virtualization windowing props (initialNumToRender={15}, maxToRenderPerBatch={10}, windowSize={5}, removeClippedSubviews={true}) to the <FlatList /> components in src/screens/FlightScreen.tsx, src/screens/PasswordScreen.tsx, and src/screens/CalendarScreen.tsx.

🎯 Why:
To prevent unnecessary re-renders and reduce memory consumption when rendering large lists of data (like flights, passwords, or schedule data). The default windowSize (21) renders too many items off-screen, which can cause frame drops. Limiting batch sizes and enabling removeClippedSubviews ensures only the necessary items are kept in memory and rendered.

📊 Impact:
Significantly reduces memory footprint and improves scrolling performance on these three screens by preventing off-screen items from consuming resources.

🔬 Measurement:
Run the app and navigate to the Flight, Password, or Calendar screens. Observe improved smooth scrolling and lower memory consumption when the lists contain a large number of items.
