Swipe in from the side edge to change pages on the Guition (0.2.29)

Page swipes were an LVGL gesture anywhere on the screen: 50 px, fast only,
and almost always starting on a tile that lit up as pressed. On the Guition
a touch that starts within 32 px of the left or right edge and travels
40 px inward, clearly sideways, now flips one page (from the right edge
leftwards is next, from the left edge rightwards previous), at any speed
and in every rotation; a swipe that starts in the middle does nothing, so
taps and drags on tiles can no longer change the page by accident. The
whole-screen gesture is removed from the Guition profile; the CYD keeps
it. Firmware 0.2.24 for both boards, the app only reworded the setting.

+Alleen firmware (Guition). `cyd::EdgeSwipe` (in `cyd_ui.h`, getest in
+`test_cyd_ui.cpp`) vervangt op de Guition de LVGL-gesture op `home_page`: `begin()`
+in `on_touch` met de LVGL-rotatie, `update()` in `on_update` voor het eerste contact;
+bij een treffer `touch_guard.consume()`, `lv_indev_wait_release()` op alle indevs en
+`show_tile_page`. Substituties `EDGE_SWIPE_BAND_PX`/`EDGE_SWIPE_TRAVEL_PX`;
+`DISPLAY_W`/`DISPLAY_H` bepalen de rotatiemapping (ESPHome: 90° `x=y, y=W-x-1`,
+270° `x=H-y-1, y=x`, 180° spiegelt beide). De CYD houdt de LVGL-gesture. De
+instelling `swipe_pages` blijft de schakelaar; protocol, opslag en sleutels ongewijzigd.

 Alleen firmware. `cyd::TouchGuard` krijgt `configure(move_limit_px, min_press_ms)`
