fix: standardize billing order status values and fix expiration lookup

- billing_integration.php: admin-created servers now use status='Active' (was 'installed')
- home_handling_functions.php: expiration query uses status IN ('Active','Invoiced') only
- my_account.php: renewable_statuses includes canonical 'active'/'invoiced'; legacy labels updated
- admin_orders.php: add orphaned home_id diagnostics section
- normalize_billing_order_status.sql: new migration to convert installed/paid→Active, suspended→Invoiced

  * This does NOT re-provision the server — the caller (add_home.php) already
