Fix UI Rendering Issue (Issue #693)

Fixed issue where the last item in menu lists doesn't render properly:\n- Added bounds checking for item height and width\n- Fixed image rectangle dimensions for last items\n- Added proper clipping to prevent drawing outside item boundaries\n- Ensured valid dimensions for all menu item parts
