Refine dashboard hero, mobile nav, animations and touch polish

- Stack the /me dashboard hero (avatar + info) on small screens instead of
  crowding them side by side; center the avatar and info on mobile
- Respect prefers-reduced-motion in the Reveal scroll animation
- Make the desktop pitch-in (NavDropdown) and mobile menu more consistent;
  give the mobile menu a max-height with overscroll containment so long
  navs scroll instead of overflowing on small phones
- Add safe-area insets for notched devices on header, nav and footer
- Polish whole-link content-cards (community tiles) with hover lift and a
  visible focus ring
- Enforce a comfortable min touch height on all .btn buttons
