HEAD history - since - query

There was a sprint focused on cache where implementations of HEAD requests were required. Artifacts remain in the API controller for /since, /history, and /query HEAD requests.

I believe it has been determined that these are not valid HEAD requests. HEAD requests are only for single pieces of data behind a PURL. If we aren't going to use them, we should delete them.

Comienza en el controlador de API que gestiona /since, /history y /query, e inspecciona cómo se registran sus solicitudes HEAD. Elimina los handlers HEAD obsoletos y verifica que estas rutas ya no expongan esas solicitudes, mientras su comportamiento restante no cambia.
