light wallpapers: v4 color formula

Browse Source 
all 6 light wallpapers recalculated with the new formula: received
messages are white (read more often, max readability), sent messages
muted in the hue — same pattern as Telegram. tint/chroma tuned per
wallpaper on device.

the formula lives outside the app (node script), only the resulting
oklch constants are in kotlin. LIGHT is served from _background/_tint/
_colors; DARK/SIMPLEX/BLACK keep the generator.
