⚡ Bolt: [performance improvement] Stabilize callbacks for memoized list items

[TargetMisser]

💡 What: Wrapped openAdd and openEdit in useCallback in PhonebookScreen.tsx and modified PasswordRowComponent to prevent inline arrow function creations on every render in PasswordScreen.tsx. Added comments to document these optimizations.
🎯 Why: In React Native, passing unmemoized inline functions (like () => openEdit(item)) as props to components wrapped in React.memo (like PasswordRow and ContactRow) defeats the memoization, as the function reference changes on every render. This causes the entire FlatList to re-render all items needlessly when unrelated state changes.
📊 Impact: Prevents cascading re-renders of list items in PhonebookScreen and PasswordScreen, significantly improving scrolling and filtering performance for large lists.
🔬 Measurement: Use React Developer Tools Profiler to observe that list items no longer re-render when typing in the search bar or toggling the add/edit modal.
