web-next: paridad de los campos de login con el tema Django

- Turnstile: quitar clases Tailwind del wrapper (my-3/flex/justify-center)
  → estilo inline neutral centrado, como la web Django.
- login/register/recover: el boton ya NO arranca deshabilitado (gris) por
  falta de captcha; se ve activo como en Django. El captcha lo sigue
  validando el servidor (devuelve captchaFailed). Se quita el SITE_KEY
  cliente ya innecesario.
- reset-password: pagina que habia quedado sin migrar (usaba nw-btn/
  nw-input/mx-auto/text-amber) → PageShell + middle-center-table + inputs
  planos + recover-button + alert-message, igual que el resto del flujo.
