/*
 * billing_integration.php
 *
 * Shared helper for recording admin-created game servers in the billing tables,
 * so they are treated identically to FREE website orders:
 *   billing_invoices (status='paid', amount=0)
 *   billing_orders   (status='installed', price=0)
 *
 * This does NOT re-provision the server — the caller (add_home.php) already
 * created the server via the panel DB layer. We only write the billing ledger
 * entries so admins can track every server in one place and cron-shop.php can
 * manage renewals/suspensions uniformly.
 *
 * Usage (inside exec_ogp_module after $new_home_id is confirmed):
 *   require_once 'billing_integration.php';
 *   admin_register_server_in_billing($db, $user_id, $home_cfg_id,
 *       $rserver_id, $home_name, $max_players, $access_rights, $ftp, $new_home_id);
