Let LVGL decide a tap on the Guition: release inside the tile counts (0.2.33)

A firm press on Studio 1 that drifted 73 px was still refused by the touch
guard's movement limit. On a capacitive panel that limit has no job left:
the edge swipe consumes its own tap, sliders capture their own drag, and
LVGL already drops the click when the finger leaves the tile. The guard's
limit can now be 0 (no limit); the Guition profile sets it so, the CYD
keeps 56 px because its resistive panel jumps. Firmware 0.2.28 for both
boards; the app only moves its target version.
