fix(subscription): plan cards fill row, popular = professional

- Replace wrapping flex (maxWidth cap) with a fills-the-row grid
  (repeat(auto-fit, minmax(230px, 1fr))) so the three cards sit in one row
  and grow to the content width — removes the empty gap and stray wrap
- Move the most-popular highlight to the professional (top) plan, matching
  clinic-pro-tauri
