New Repositories Page and Redirect Updates

## What's New
We've added a dedicated Repositories page, allowing users to manage all their repositories in one place. This new feature simplifies access and offers a better overview of the repositories you have access to. Users can now view their enabled and disabled projects and easily navigate to relevant actions.

Additionally, the Dashboard has been streamlined to redirect users to the new Repositories page instead of the previous dashboard, making navigation more intuitive.

## Improvements
To enhance the reliability of interactions with the GitHub API, we've introduced retry logic for handling server errors (500, 502, 503, 504). This ensures that users experience fewer disruptions when using the application, especially during times of server instability.

## Bug Fixes
We've corrected the redirect behavior to ensure that users remain on the same page after performing repository actions. This improvement enhances the overall user experience by maintaining context during navigation.
