feat(blog): add admin endpoint for blog details and cache invalidation

- Implemented `adminDetail()` method in `BlogController` to retrieve blog posts of any status for admin editing.
- Introduced `BlogCacheInvalidator` service to handle cache invalidation after blog create/update/delete actions.
- Updated existing methods in `BlogController` and `RepresentationBlogController` to call cache invalidation on blog modifications.
- Enhanced `BlogFormPage` and `RepresentationBlogFormPage` to utilize the new admin endpoint for fetching blog data.
- Added tests for `BlogCacheInvalidator` to ensure proper functionality and error handling.
- Updated documentation to reflect new API endpoint and cache invalidation behavior.
