Refactor error handling for invoice period flag and item row fetching, improve cURL timeout

- Simplify error handling in `invoice_period_flag_service` by directly returning empty arrays on exceptions, removing redundant cache warm-up logic.
- Increase `CURLOPT_TIMEOUT` to 30 in `economic_m.php` for more reliable network requests.
- Adjust unit tests to reflect updated cURL timeout value.
