feat(landing): 230px fullbody roster, features goat column, trimmed header

- Members roster avatars render 230px tall (full body); NMSR size bumped to 256
  and tiles widened to fit the portrait.
- Features section is now two columns: the 4 feature cards stacked on the left, a
  Minecraft goat image on the right (public/Goat_JE1_BE1.webp). Stacks on narrow
  screens.
- Header nav links trimmed to How to Join + Status; the auth CTA cluster is now
  Register / Account / Play (the old "Log in" button relabeled Account →
  Cuenta/Kontua).
