Add the talk to the landing showcase; point Atlas at its subdomain

- Landing 'From hackerspace.sh' showcase: add a 'Hacking Your Hackerspace'
  tile (07 projects) linking the deck on hack.build, with a new HackBuildIcon
  (the brand's pink open-end wrench).
- Point the Atlas tile at https://atlas.hackerspace.sh (now live) instead of
  the old internal /atlas route.
- Use the same hack.build wrench for the talk card on the Resources page.
