refactor: move cache directory path from view to provider

Move cache directory path resolution from CacheInfoView to RepoListScreenDataProvider.
This allows tests to mock the cache directory path instead of displaying the actual
home directory path.

Changes:
- Add cache_dir field to RepoListScreenData
- Update RepoListScreenDataProvider to resolve cache directory path
- Update RepoListScreen to store and pass cache_dir to CacheInfoView
- Update CacheInfoView::render to accept cache_dir parameter
- Update test mock to provide fixed cache directory path
- Update snapshot test to use fixed path "/home/user/.gittype/repos"

Benefits:
- Views no longer depend on environment-specific paths
- Test snapshots are deterministic and portable
- Better separation between data fetching and presentation
