webserver refactoring: Retire using `get_services_for_user_in_product`

[pcrespov]

Follows up from #7836 where we added a cache to get_services_for_user_in_product

Example of how can be replace get_project

@routes.get(f"/{VTAG}/projects/{{project_id}}", name="get_project")
@login_required
@permission_required("project.read")
@handle_plugin_requests_exceptions
async def get_project(request: web.Request):
    """

    Raises:
        web.HTTPUnprocessableEntity: (422) if validation of request parameters fail
        web.HTTPNotFound: User has no access to at least one service in project
