feat: add Request_API dispatcher and internal API URLs

Replaces urllib http_client with proper Request_API class in general/request_api.py
using the requests library. Adds API_BACKOFFICE, API_COMUNICACIONES, API_DOCUMENTACION
settings pointing to Docker service names. Adds requests==2.32.3 to requirements.
