feat(landing): rework — es default, 2-step join, roster + account polish

- Default language Spanish at root /, English moves to /en/ (eu unchanged):
  getStaticPaths {lang:undefined}->es + LANG_*_PATH maps swapped in ui.ts.
- Section order: hero -> join -> status -> members -> mods -> features.
- Join flow 3 -> 2 steps (drop the Connect/IP step; launcher handles the
  address). Remove the hero IP CopyChip. Header CTA renamed Play/Jugar/Jolastu
  and gains Register + Login links on all four pages.
- Account page: hide the whole login block once authenticated (not just the
  form), add an avatar Refresh button (cache-busted NMSR re-fetch), flatten the
  avatar (no bevel). New i18n key account.refresh.
- Register page: new REGISTRATION_SHOW_INVITE env (default false/hidden) toggles
  the invite-code field independently of the REGISTRATION_MODE backend gate.
- Members roster: drop the `admin` account, render full-body via a new
  ROSTER_AVATAR_MODE (default fullbodyiso); portrait tiles.
- Style: flatten emboss on feature icons (.picon) + player tiles (.roster-tile).
  PixelIcon gains optional image support (/icons/<name>.png|svg).
- Favicon now /favicon.png (committed) on all pages.
- Docs: plan/09-landing.md Assets section (logo/favicon/features-icons drop
  points) + default-language note; .env.example documents the two new vars.
