Ordrivo GastroFlow Pro 7.3.1 — WPBay follow-up fixes

- The desktop front-end cart now renders the current cart lines and total, including a saved cart after page reload.
- The Order Terminal now renders active orders into New, Preparing and Ready columns. Accepted and preparing orders appear in Preparing; ready orders appear in Ready.
- The Shortcodes menu and helper page use English source labels and instructions.
- Reservation form submission safely creates a status message when one is missing, preventing the reported setAttribute null error.
- Reservation submit controls have explicit visible button styling to resist theme CSS hiding them.
