Pull upcoming-job footprints plus full order/client/agent detail from Inspection Support Network (ISN) beyond the basic schedule+report connect

Steps

1. If you don't already know the customer's ISN Company Key and Service Domain, request an integration username/password from ISN (sys@inspectionsupport.net) to call the Admin API documented at http://api.isnadmin.com
2. GET the Admin API's isn/url endpoint with the company key to resolve the client's Service Domain (e.g. 4isn.com); skip this step entirely if you already know the domain
3. Construct the tenant REST endpoint as {service_domain}/{company_key}/rest, documented at http://api.inspectionsupport.net/, and authenticate with an Access Key/Secret Access Key pair (preferred over raw username/password)
4. Call GET /orders/footprints to retrieve stub records for the inspector's upcoming inspections
5. For each footprint, call GET /order/{id}, /client/{id}, and /agent/{id} to hydrate full order, client, and agent detail
6. After processing a footprint, call its DELETE endpoint — ISN only auto-purges unclaimed footprints after a customer-configurable retention window
