fix: replace emoji with hero image in blog sidebar doctor card

- Post.cshtml.cs: load hero image, tag from SiteSettings in SetViewDataAsync
- Post.cshtml: show <img> with hero image in .doc-avatar when set,
  fall back to emoji only if no image is configured
- .doc-avatar: circular crop with object-fit:cover, gold border
- doc-title now uses HeroTag from settings (not hardcoded)
