Subject: test(ui): drive the simulator with a scripted flow and check every
 screen

tools/ui_flow.py clicks buttons and taps from the device files, waits for
DIAG shown lines and compares 10 screens per watch with goldens on four
test and three spot-check devices. Adds the fixture-wrap generator, UI
logic tests and driver tests; the launcher opens apps from their glance.
