AirTrack BugTracker V2

provision_linux() emails license.lic but never calls the Wombat API to create a customer record or set up entitlements. The customer receives no CUSTOMER_ID in their email. .env.example has AIRTRACK_CUSTOMER_ID= (blank) with a hint, but the customer has nothing to put there and no Wombat record exists for them. Fix: provision_linux() should call Wombat /api/wombat/provision to create a customer, auto-entitle their local registry (matching the auto-entitle logic already built for Windows), and include the CUSTOMER_ID in the email.
