fix(blog): replace IApplicationUser Author with concrete BlogPostAuthorDto System.Text.Json cannot materialise an interface without a polymorphic converter. Until this commit, BlogPostDto.Author was typed as the abstract interface IApplicationUser, which crashed the "load posts" call in PostIt whenever the server returned a post with a populated Author object (the common case — GET /api/BlogApi). Fix: * Introduce a minimum-viable wire DTO BlogPostAuthorDto in Yavsc.Abstract.Blogspot (record: Id, UserName, Avatar). These are the only fields the client UI actually needs; the server-side ApplicationUser navigation is preserved for permission checks and authorisation. * Change IBlogPost.Author and BlogPostDto.Author from IApplicationUser to BlogPostAuthorDto? (interface change, breaking). The EF entity BlogPost keeps its full ApplicationUser navigation property and exposes IBlogPost.Author via an explicit interface implementation that projects to BlogPostAuthorDto on demand (so EF can still lazy-load the navigation without forcing an eager join on every read). * Restore the using directive that was accidentally removed when the BlogPostDto property was rewritten (needed for ICircleAuthorization in GetACL()). Regression coverage (the missing test Paul flagged): * Add BlogPostAuthorDtoTests in PostIt.Tests with four scenarios that exercise the wire shape on the client side: - A BlogPostDto JSON with a populated Author round-trips through JsonSerializer without throwing and the three fields (Id, UserName, Avatar) survive intact. - A BlogPostDto JSON with explicit "author": null deserialises with Author == null. - A BlogPostDto JSON without any Author field at all deserialises with Author == null (forward compat). - The serialised shape of BlogPostAuthorDto uses camelCase property names (matching the server's Web defaults), so the field names on the wire don't drift without a test catching it. Tests: 55/55 PostIt.Tests (+4 new), 24/24 Yavsc.Blogs.Tests, 44/44 Yavsc.Org.Tests. No regressions. Side note: yavsc.sln picks up Yavsc.Api.Client (added by 'feat/postit-acl' in 1.0.7 but never registered in the solution file until now — probably auto-added by a recent 'dotnet build' that discovered the .csproj).
