feat(commits): enhance commit listing with pagination and skipping

This update introduces pagination and skipping functionality for the
commit listing feature, allowing users to load commits in pages and
navigate through them more efficiently. The UI has been adjusted to
support loading more commits dynamically, improving the overall user
experience when dealing with large repositories.

- Added pagination support for commit history
- Introduced a loading mechanism for fetching more commits
- Updated UI components to reflect changes in commit loading behavior
