Change calibration gesture from double-click to 7 quick presses

Auto-calibration drives the window through full travel, so the trigger
must be hard to hit accidentally. The 3-10s Wi-Fi wipe hold on the same
button is unchanged; timings still cannot overlap.

+  is now deliberately hard to hit by accident; a stray double-tap no longer
