refactor(details): use domain model for profile caching and cleanup DTOs

This commit simplifies the user profile data handling by using the `GithubUserProfile` domain model directly for caching and removing redundant DTOs and mappers.

- **refactor(details)**: Removed `GithubUserProfileDto` and its associated mapper.
- **refactor(details)**: Updated `DetailsRepositoryImpl` to cache and retrieve `GithubUserProfile` directly instead of using a DTO.
- **feat(core)**: Added `@Serializable` to `GithubUserProfile` and `PaginatedDiscoveryRepositories` to support serialization/caching.
- **chore**: Cleaned up unused imports in `ProfileRepositoryImpl` and `DetailsRepositoryImpl`.
