Feed the edge swipe from the touchscreen triggers again (0.2.34)

Browse Source 
The 0.2.32 edge swipe listened on LVGL's input device, but the LVGL 9.5.0
bundled by ESPHome sends the indev PRESSED and RELEASED without PRESSING,
so the swipe never received a position update: on Studio 1 the log showed
the GT911 press and then nothing. The Guition follows the swipe through
on_touch, on_update and on_release again, the route that worked live in
0.2.24 once the card-close fix was in, with ESPHome's own rotation mapping,
the 45-degree rule, end() on release so a stale armed state cannot fire on
the next touch, and the "genegeerd"/"niet gevuurd" log lines. Firmware
0.2.29 for both boards; the app only moves its target version.
