refactor: standardize pagination response structure and enhance cursor handling

- Update various services and hooks to replace 'items' with 'list' for consistency in pagination responses.
- Modify PostRepository, commentService, groupService, messageService, and postService to align with the new response structure.
- Enhance cursor pagination logic in hooks and components to ensure proper handling of pagination states.
- Refactor HomeScreen, PostDetailScreen, SearchScreen, and other components to utilize the updated pagination structure.
