web-next: rename-character/customize-character por SumUp + renombrado de rutas

- /rename-character y /customize-character: renombrar/personalizar pagados por SumUp
  (getRenamePrice/getCustomizePrice). SumUp ahora es service-aware: columna
  home_stripelog.service; createSumUpCheckout guarda service+character;
  fulfillSumUpCheckout despacha a la acción del servicio (.char rename/customi) o,
  sin service, acredita PD. [service]/checkout acepta provider:'sumup';
  PaidServiceForm acepta provider+confirmText; service-success maneja el return SumUp.
  Se eliminan las antiguas /rename y /customize (Stripe).
- /revive-character (comparte ReviveServiceContent); se elimina /revive.
- Renombres de ruta + todos sus enlaces:
  /account -> /my-account, /recruit -> /recruit-a-friend, /unstuck -> /unstuck-character.
  (/select-account y /api/account/* intactos.)
