[Tablet support M3] Part 4 – Order summary product buttons update

[samiuelson]

Closes: #10618

Description

This PR adjusts the appearance of the products section's buttons in tablet mode:

• "+ Add products" button is visible only on a phone. On tablet, the product selector is open all the time, so it's redundant.
• "Scan products" is visible as an icon on the phone and a full button on the tablet.

Testing instructions

Verify that the buttons are shown correctly on tablet and phone.
