Cambio de email con doble confirmación (completa el bloque de auth)

- lib/change-email.ts: requestEmailChange (valida pass/email/token, crea activación
  con old_email/old_email_hash, email al correo actual), confirmOldEmail (marca is_used,
  email al nuevo), confirmNewEmail (re-deriva verifier con el nuevo email + actualiza
  battlenet_accounts y account; borra la activación).
- components/ConfirmClient.tsx: cliente genérico que confirma un hash por POST al abrir.
- Routes /api/account/change-email, /confirm-old-email, /confirm-new-email.
- Páginas /change-email (protegida) y /confirm-old-email, /confirm-new-email (auto).
- Catálogos ChangeEmail, ConfirmOldEmail, ConfirmNewEmail.

Verificado: change-email protegida (401/redirect), confirmaciones con hash inválido
-> invalidLink sin crash. AUTH 100% reimplementado en Next.js.
