refactor(theme-studio): drop the too-similar-colors warning box

The warning box under the palette wasn't useful there; the same ΔE info is reachable per-chip via the nearest-ΔE tooltip and inline contrast. Remove renderPaletteWarnings, the #palwarn element, its CSS, and the #deltatest gate. paletteWarnings still runs for the per-chip nearest distance.
