Review and update Total messages chart on dashboard and usage.html with new data from backend

[heyitsmebev]

This needs to be updated with the new data points from the backend. One is for messages and the second is for allowance limit.

This chart is currently pulling data from this def:
def service_dashboard(service_id):

ken provided the endpoint: service_api_client, get-service-message-ratio

Note:
Do we still need usage.html page? If not, we can remove def usage(service_id): and usage.html

look into get_annual_usage_breakdown
get_usage_breakdown_by_type
@main.route("/organizations/uuid:org_id
anything with this page? http://localhost:6012/platform-admin/reports/usage-for-all-services
class BillingAPIClient(NotifyAdminAPIClient):
def get_services_and_usage(self, org_id, year):

Look into it being removed from tour pages
