This guide refers to two databases `iot_center` and `iot_center_auth`, but the project’s committed defaults/README use `iot_center_devices` for the auth database (`INFLUX_DATABASE_AUTH`). Update the diagram and any commands/env examples so the database names are consistent with `.env.development`.

Inspect the guide, README, and .env.development to find the diagram plus database commands and environment examples. Replace the auth database name with iot_center_devices wherever needed, then verify all documented names match the committed defaults.
