feat(settings/profile): move share to per-product, profile share on card header

- Each product row now has an ↗ share button (product URL shared, not profile)
  WhatsApp message: "Found this for our baby — [title]: [url]"
- Only one product share sheet open at a time; closes on backdrop tap
- Profile page share (↗) moved to the profile card header row where it
  contextually belongs — shares the /m/slug link, not a product
- Removed the share button that was on the Products section header
