[Icons] Author icon emphasis colors as palette roles

The emphasis levels were computed from the accent at paint time, so a
theme could not vary them: every theme got the same derived strong and
soft tones, and a semantic hue was pushed toward the accent whether the
author wanted that or not.

Give each family three authored roles instead. Icon/IconStrong/IconSoft
carry the neutral glyph ink and Positive/Negative gain the same Strong
and Soft companions. Emphasis becomes a lookup inside the family, and a
caller that names a variant pins that level at every emphasis. The paint
path returns the authored color verbatim; only the filled treatments keep
their saturation floor, because carrying a disc or a fill is a treatment
decision.

Shipped palettes author the full ladder for both schemes; the palette
editor exposes the new rows and the generator writes them. System keeps
deriving its neutral ink from the platform palette, since it ships no
palette of its own.
