Fix View Repo outline, social-share icon stroke, and owner avatar sizing

- .project-github-button renamed to .project-repo-button (added 1px border
  for proper outline style; the old class is gone so the button was rendering
  as unstyled <a>).
- Suppress inherited stroke on the Tabler SVG <rect> viewport marker — without
  this it draws a square outline inside the round social-share button.
- Move owner avatar inline styles into CSS with object-fit: cover, explicit
  width/height, and border-radius: 50%; add flex shrink/grow rules for the
  owner row's three spans so the avatar isn't squashed by the flex layout.
