rename-guild: permitir pagar con PD, Stripe o SumUp

Renombrar hermandad ya no es solo PD: ahora ofrece el mismo selector de
forma de pago que el resto de servicios (saldo PD / tarjeta Stripe / tarjeta
SumUp). El coste es equivalente: 1000 PD = 10 €.

- lib/guild: se separa la validación (checkGuildRenameEligibility) del
  renombrado por SOAP (renameGuildBySoap); nuevo GUILD_RENAME_EUR (10 €).
- paid-services: entrada 'rename-guild' para que la reconciliación/webhook
  entregue el servicio tras el pago con tarjeta.
- nueva ruta /api/guild/rename/checkout con las 3 pasarelas (valida
  elegibilidad antes de cobrar); se elimina la antigua /api/guild/rename.
- RenameGuildForm usa PaymentMethodSelect y redirige a service-success.
- i18n: Paid.rename-guild (title/success) para la página de éxito.
