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.
