- Enhanced InternetPlanCard to better format plan names and display features dynamically.
- Updated InternetConfigureContainer to include a back button and improved plan header presentation.
- Refactored ServiceConfigurationStep to enhance the display of important information for Platinum subscribers and improve access mode selection.
- Streamlined styling and layout across components for better visual consistency and user experience.
