Formularios: noValidate en todos para usar red-response del sitio

Desactiva la validación nativa del navegador ("Rellene este campo", formato de
email) en el resto de formularios (recover, reset-password, trade-points,
rename-guild, transfer-dp, gold, promo, transfer, quest, send-gift, 2FA, restore).
Los errores se muestran como red-form-response (por validación en cliente o del
servidor), consistente con login y create-account. Botones ya gateados por campos.
