[g123k]

Hi everyone!

The initial goal of this PR was to show the product type… but as always, there's more than that.

Footer

Visible Product type

Smaller AppBar on scroll

Body

The huge barcode is removed 🎉

Footer

A button provides access to multiple actions (in the future: it would be nice to be able to flag an incorrect type or to view data quality tags)

Button or swipe gesture

Barcode viewer

Misc

This PR adds some icons for the License screen
