web-next: migrar toda la UI al tema real nw-ryu

Reescritura completa del frontend Next.js del sistema visual Tailwind
"simulado" al tema Django original (nw-ryu), para paridad pixel con la
web actual antes del cutover.

- Tema real: copia de static/nw-themes/nw-ryu + favicons a public/, el
  layout carga el novavow-style.css real de ultimo (gana la cascada sobre
  Tailwind) + Font Awesome.
- Shell replicando los partials Django: SiteHeader, Video, Social, Footer,
  ServerClock; home con estructura real (main-page/middle-content/...).
- Helpers reutilizables: PageShell (main-page > middle-content > body-content
  > title-content) y ServiceBox (title-box-content + back-to-account).
- Paginas migradas a clases reales del tema (fieldset/tool-button/char-box/
  item-box/info-box-light/max-center-table/alert-message/botones reales),
  eliminando el markup Tailwind (.nw-btn/.nw-card/.nw-input):
  auth (login/register/recover/reset/select-account/activate),
  cuenta + servicios de personaje (revive/unstuck/rename/customize/
  change-race/change-faction/level-up/gold/transfer + pago Stripe),
  ajustes (change-password/change-email/security-token),
  comunidad (vote-points/recruit/battlepay), foro completo, y
  admin (indice + 7 secciones + los Admin*Manager).
- Se conserva el bilingue (next-intl); claves nuevas en messages/es|en.json.

Verificado: typecheck + build OK; rutas protegidas 307->login; sin
MISSING_MESSAGE; cero Tailwind residual (solo .nw-tool-btn/.nw-page,
clases propias en globals.css).
