fix(redis): update the kv-store defaults in docker vs. app

Changing to set the default `KvBufferStore` to redis in the docker-compose and `fs` in the app. We cannot guranatee redis is running if the app is run as standalone, but can ensure `redis` is up and running in the `docker-compose`. Also updates the redis volume to use the proper default `data/` path where `rdb` files get saved. We may want to consider setting the `appendonly` flag when starting `redis`.
