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

+-- normalize_billing_order_status.sql
+--
+-- One-time migration: standardise gsp_billing_orders.status to the canonical
+-- three-value set used by cron-shop.php, create_servers.php, and the game
+-- monitor expiration lookup:
+--
+--   Active   – server provisioned and billing current
+--   Invoiced – renewal invoice open; service still running
+--   Expired  – invoice unpaid past grace period; server suspended/awaiting deletion
+--
+-- Legacy → canonical mapping applied by this script:
+--   'installed'  → 'Active'   (provisioned via old invoice-first flow)
+--   'paid'       → 'Active'   (payment captured but before explicit provisioning step)
+--   'suspended'  → 'Invoiced' (overdue; renewal invoice was open — maps to Invoiced
+--                               so cron Step B will expire them on the next run if
+--                               still unpaid, rather than silently treating them as Active)
+--
+-- All other statuses ('in-cart', 'cancelled', 'refunded', 'Active', 'Invoiced',
+-- 'Expired') are left unchanged.
+--
+-- Compatible with MySQL 5.7+ and MariaDB 10.2+.
+-- Table prefix is hardcoded to gsp_ (standalone billing module context).
+-- Run ONCE on an existing installation; safe to run again (no-op on clean data).
