perf(profile): improve rendering performance and selector efficiency

Optimize profile-related screens and components by implementing memoization and granular Zustand selectors to reduce unnecessary re-renders.

- **Performance Optimization**:
  - Wrap `TabBar` in `React.memo` to prevent re-renders when parent components update.
  - Refactor `UserProfileScreen` to use a memoized `ProfileListHeader` component, decoupling the user header from tab state changes.
- **State Management**:
  - Replace object destructuring from `useAuthStore` with granular selectors (e.g., `useAuthStore((s) => s.logout)`) in `AccountDeletionScreen`, `EditProfileScreen`, `FollowListScreen`, and `SettingsScreen` to prevent re-renders on unrelated store changes.
- **Code Cleanup**:
  - Remove redundant case logic in `useUserProfile` hook.
