A real choice to customize

On a saved Build a Box or Fixed Bundle plan, the widget preview card's Customize button used to only send a support message, with no way to jump straight to the storefront customization editor for that widget.

Clicking Customize now opens a small chooser: "Open editor" takes you straight to Storefront customization for that widget in a new admin tab, so you can adjust its appearance directly, while "Contact us" still sends the same message to support as before, for when you'd rather ask for help.

We also fixed a related issue where arriving at Storefront customization through a plan page's customize link, then clicking Customize widgets on the already-preselected card, did nothing at all; it now opens the widget editor on the first click.
