Pull customer utility bill and interval meter data from UtilityAPI with customer authorization

Steps

1. Create a UtilityAPI account and obtain an API token; use it as a Bearer token in the Authorization header for all requests.
2. Generate an authorization form URL via POST /api/v2/forms, specifying the utility, template settings, and a callback URL; send this URL to the customer so they can authorize data sharing with their utility.
3. Poll GET /api/v2/authorizations or listen for a webhook callback to detect when the customer completes authorization; the authorization object will contain a UID needed for subsequent data requests.
4. Request bill data via GET /api/v2/bills?authorizations=<AUTH_UID> and interval data via GET /api/v2/meters/<METER_UID>/intervals to retrieve historical consumption.
5. For ongoing data collection, use UtilityAPI's webhook or scheduled collection features to receive new bills and interval data as the utility makes them available.
