Fix favorite filter and tag filtering in blog post repositories

Refactored tag and favorite user filtering logic in both EfCore and MongoDB blog post repositories to handle empty filter results and cancellation tokens more robustly. Updated BlogPostPublicAppService to pass favoriteUserId to GetCountAsync for accurate paging. Adjusted blog index view to improve favorite filter button visibility and logic.
