[FIX] point_of_sale: prevent order update when customer screen is open

Previously, the order line quantity would inadvertently update if the
Customer list screen was opened without clicking the search bar and
typing numbers. This commit resolves the issue by disabling the event
handler while a temp screen is open. Also, it enhances usability by
focusing on the search bar upon opening the Customer list screen.
