Attachments can now only be added when a blog post is created: POST /api/c_blog_posts takes a multipart request (title, fullText, blog, files[], comments[]) and creates the post and its files in one transaction. The standalone POST /api/c_blog_attachments/upload is removed, so files can no longer be added to an existing post. This matches 1.11.x, where attachments are only set by the author in the post creation form. The blog UI (createPostWithFiles) now sends a single request; the edit dialog already had no file picker.
Note: POST /api/c_blog_posts no longer accepts a JSON body; the blog UI was its only client.
