feat: align LanguageSettingsScreen header and layout order with Figma designs

[prince-0408]

Description

This PR addresses issue #674 by aligning the LanguageSettingsScreen UI layout and header title with the official Figma designs.

Key Improvements:

• Header Title Formatting: Updated the top page header title format from {Language} (e.g. English) to {Language} settings (e.g., Deutsch settings, English settings) as specified in the Figma design system.
• Layout Section Item Reordering: Re-ordered the list items under the Layout section in getLayoutListData() to match the exact Figma visual hierarchy:
  1. Default keyboard (Default layout)
  2. Default currency symbol
  3. Period and comma on ABC
  4. Disable accent characters (conditionally displayed for German, Swedish, and Spanish)
• Extensible Navigation Callback: Introduced an optional onDefaultLayoutSelect callback parameter to LanguageSettingsScreen for seamless future navigation handling.
