Scan audio: outcome-based — yoo-hoo on resolve, 'uh-oh' on no-match

Moved the success chime from lock-in to the resolve branch (only plays when the
code actually finds a product) and added a distinct low descending square-wave
'uh-oh' when a code locks but matches nothing (or nothing is read). Refactored
into a shared tone() player.
