chore(types): regenerate reference DTOs from gateway refactoringV2 1c4e974f7

Refreshed in update mode against a private gateway stack on the same head
(header options kept; BaseUrl left at the usual localhost value).

- cultureCode gone from every request (language is Accept-Language only)
- end-user push devices + messages (RegisterOwnPushDeviceRequest & co.)
- RepairContactRolesRequest (POST /membership/users/repair-roles)
- public echo without licence fields
