Repository Limit Adjustments and UI Updates

## Improvements
In this version, we've made significant adjustments to how repository limits are calculated. The system now ensures that plan limits only consider owned repositories, rather than team repositories. This change provides users with a more accurate representation of their project capabilities based on their individual plan tier.

Several user interface updates have also been implemented to enhance navigation and usability. For instance, the onboarding experience now features a cleaner layout, making it easier for users to manage their repositories effectively. The billing interface has been updated to streamline the process of managing payment methods and viewing invoices, with improved button designs for better interaction.

Moreover, we've refined various elements throughout the application, such as updating links and enhancing the layout for a more cohesive and visually appealing experience. These changes collectively aim to make your interactions smoother and more intuitive.

Overall, this release focuses on delivering a more user-friendly experience while ensuring that your repository management aligns accurately with your plan's capabilities.
