Add four animated Cyberpunk-style ESPHome pages

Netrunner HUD, self-solving breach protocol, optics boot-and-scan and a
split HUD with a mini breach matrix, all in the page rotation. The el512
display gains animated_pages / animation_interval (redraw ~15 fps while
shown), page_age_ms() as animation clock, and shift_rows() / invert_rect()
for glitch effects.

+## Cyberpunk pages
+
+Four animated ESPHome pages in a Cyberpunk look, drawn by
+[components/el512/cyberpunk.cpp](components/el512/cyberpunk.cpp) with Orbitron, Rajdhani
+and Share Tech Mono (Google Fonts). All of them take part in the rotation:
+
+- **Cyber HUD**: clock, outside weather, power (solar, house, grid) and four rooms
+  in cut-corner frames, with a scrolling ticker.
+- **Cyber Breach**: a breach-protocol code matrix that solves itself: the cursor
+  walks the active row or column, codes fill the buffer, daemons upload, then a new
+  puzzle starts.
+- **Cyber Scan**: an optics boot log with live values, a calibration zoom, then a
+  rotating reticle around the clock and a typed-out scan of the house.
+- **Cyber Split**: compact clock and readouts on the left, a small breach matrix on
+  the right.
+
+They are listed under `animated_pages`, so they redraw about 15 times a second
+while shown; each page starts its intro (wipe-in, glitches) when it appears. The
+fonts and Home Assistant values come from the globals `cp_fonts` and `cp_home` in
+`el512-panel.yaml`. To keep only some of them, remove the others from `pages`,
+`animated_pages`, the page select, `on_page_change` and the rotation loop count.
+
+These pages are inspired by the look of Cyberpunk 2077 and use no assets from it.
