test(ui): second UI scenario, and the fixes it found

A second UI-test build (uitest-extra.jungle) covers the legacy PIN and
the forced new PIN, Change and Reset PIN, a queued Require PIN, UPC-A,
Code 39, the code error screen, the encoding progress, auto-lock on a
barcode, the light theme and the glance without a code; the main flow
adds the Steam and Library details and the menu's text screens.

Fixed from what it found: Entry IDs tripped the watchdog with 110
entries; auto-lock didn't close a locked barcode; a queued Require PIN
showed "Confirm in menu"; locked barcodes lacked the padlock; the PIN
keypad's bottom row, the Reset PIN question, text-screen bottoms, the
glance title and the light-theme warning colour.

Goldens approved on all seven watches; only the Forerunner 70 was
re-verified after the version bump.
