Let a tap survive a centimetre of finger drift and log every refused tap (0.2.28)

Browse Source 
The touch guard dropped a tap as soon as the finger drifted more than
18 px (under 3 mm) from its very first contact point, on both boards and
regardless of the page-swipe setting; LVGL itself never cancelled these
clicks (no scrollable ancestors, gestures do not suppress clicks). A finger
that flattens or rolls while pressing was enough, and the tap vanished
without a trace in the log.

The limit is now about one centimetre per board (TOUCH_MOVE_LIMIT_PX:
Guition 67 px, CYD 56 px), measured from a reference that settles over the
first four samples; only the contact that started the touch is followed,
so a second finger no longer counts as movement; the minimum contact time
is per board too (TOUCH_MIN_PRESS_MS: 60 ms resistive, 20 ms capacitive).
Every refused tap is logged on INFO with its reason (moved, too short,
already used, bounce). Firmware 0.2.23 for CYD and Guition.
