Cleaner scan screen, Inventory and Equipment lists

The scan screen top is quieter: Chemical or Equipment is one round button, the mode switch has more room, and the Lot and name bubbles are gone on a phone. Equipment is no longer its own tab, and its list now looks like the bottle list, with Arrange by location, name, scan time or next due. On a laptop the sidebar moves you between chemicals and equipment. On a phone it is one small button that shares a row. The Inventory tab strip fades at the edge when more tabs are off screen. Flux now always shows the whole lab.
