The storefront strip's Add products and Enable app embed buttons now work

The storefront strip on the Storefront & Portal hub carries two actions when a shop needs attention: Add products to plan and Enable app embed. Pressing either now does what it says.

Add products to plan opens a confirm and, once approved, adds the strip's uncovered products into a plan the merchant picks. Because adding products to a plan can take a while on a shop with many of them, the confirm polls for up to 30 minutes and reports back; closing the confirm doesn't stop a run that already started.

Enable app embed now re-reads the shop's embed status when the merchant comes back to the tab, instead of continuing to show the old state after the merchant has already turned it on in the theme editor.

Both presses now match the strip's own labels, so a merchant acting on the strip's suggestion sees it actually carried out.
