the Phonebook feature everywhere if ngcp_type is CE

that is an array, and when specified, only the ngcp_type
roles are allowed, otherwise if not specified all ngcp types

- filter controllers from the documentation rendedring
that have allowed_ngcp_type config
specified and do not match the current ngcp type
* Role::API Role::Entities*

- check_allowed_ngcp_types() is now called in Entities and
EntitiesItem auto() and denies to 404 Path not found if
the ngcp type does not match
