Show who is at the door: camera images on the Guition (0.2.66)

Browse Source 
An alert from esp_screens_show_alert takes a `camera` (a camera.* or image.* entity): a Guition with firmware
0.2.57 shows that moment's picture across the top of the card, and a tap opens the camera full screen. A camera
or image tile opens the same full-screen view, refreshed every four seconds at a steady pace.

ESP Screen Manager fetches the snapshot with its own access, sizes it for the screen and serves a 24-bit BMP
under a random, short-lived link on port 8098; the screen loads it with ESPHome's online_image and holds no
Home Assistant token. BMP because ESPHome decodes it per chunk, where a full-screen JPEG held the loop 0.6 s.
The CYD keeps its alerts without the picture and gets no camera tiles.

The Guition also builds with ESPHome 2026.8+ again: backlight_fade.h derived from ESPHome's LEDC output, which
2026.8 made final, so the backlight now dims through ESPHome's own light transition.

Tested on the bench boards and a local add-on on the Home Assistant Yellow; docs/TEST_RESULTS_0266.md.

light gray background, white cards, and colored domain icons. From 0.2.10, you
can choose a pastel background with dark text per tile. Standby starts
after ten minutes without touch by default and is adjustable in the management page.
From 0.2.13, the backlight dims via the LEDC hardware fader (`backlight_fade.h`,
1.5 s to standby, 80 ms to wake): the full LVGL redraw on standby no longer
interrupts the transition. ESPHome's light state is synced after the fade,
so the entity in HA and later transitions stay correct.
The backlight dims through ESPHome's own light transition (1.5 s to standby, 80 ms to
wake). Firmware 0.2.13-0.2.56 used the LEDC hardware fader (`backlight_fade.h`) instead;
0.2.57 went back to ESPHome's transition, because that fader reached into ESPHome's LEDC
output, which ESPHome 2026.8 no longer allows.
The existing tile actions, climate control, and vacuum card are preserved.
Every card type works in all twenty positions.
