(feat): API-Model: Rename DTOs Step2

Description

Currently we have an outdated naming scheme for the API model DTOs: Request, Response and DTO suffix. When those DTOs are used in our model this leads to confusion.
The request and response classes are renamed to the following schema
DTOs that only contain technical keys should be suffixed with Dto,
while DTOs with resolved information should be suffixed with VerboseDto.
_

This Step rename of Gate responses and TypeKeyNameDto
