feat(landing): join-flow rework, player rosters, account page, mod list

Execute plan/18 (WS1-6) + plan/17.

- WS1: homepage join = 3 steps off packwiz (register -> UlicraftLauncher
  -> join); per-OS downloads from a synced launcher-manifest.json (schema +
  example committed); Fjord moved to its own /fjord page. Drop packwizUrl.
- WS2/3: mc-status gains an isolated /players endpoint (admin login ->
  Drasl GET /players, own client+TTL+token cache, never blocks the status
  path); online + registered rosters render shared name+avatar tiles;
  AVATAR_MODE env (default headiso).
- WS4: /account skin CRUD via browser-direct Drasl (login -> upload ->
  reset), in-memory token, players[0]; register relinks "Manage it here".
- WS5: footer link to status.${BASE_DOMAIN} in every footer.
- WS6: tooling/build-modlist.py generates mods.json + extracted logos from
  the distribution forgemods; ModList.astro renders a flat list; stat tile
  fed from the count.

Manifest/mods loaders read at build with a process.cwd() fallback (the
import.meta.url-only path does not resolve in Astro's bundled build).

New env: AVATAR_MODE, DRASL_ADMIN_USERNAME, DRASL_ADMIN_PASSWORD (mc-status
only). Generated mods.json / launcher-manifest.json / logos are gitignored;
.example.json files document the shapes. Build: 12 pages; mc-status builds.
