feat(#116): update command hooks for synchronous group response

Add CommandGroupResponse and ConfigUpdateResponse types. Switch
useSendGroupCommand and useSendRouteCommand from openapi-fetch to authFetch
returning CommandGroupResponse. Update useUpdateApplicationConfig to return
ConfigUpdateResponse and fix all consumer onSuccess callbacks to access
saved.config.version instead of saved.version.
