Add "Support GitHub Store" feature and SponsorScreen

- Created a new `SponsorScreen` component providing options for financial support (GitHub Sponsors, Buy Me a Coffee) and community engagement (voting, starring, reporting bugs).
- Integrated the sponsor section into the profile presentation layer by adding `SponsorCard` to the options list.
- Added `OnSponsorClick` action to `ProfileAction` and updated `ProfileViewModel` and `ProfileRoot` to handle navigation.
- Configured app navigation to include `SponsorScreen` in `AppNavigation` and `GithubStoreGraph`.
- Added new string resources for the sponsor page, including specific messaging for the Golden Kodee Awards.
- Cleaned up imports in `SortOrderMapper`.
