Offer the contrast level where the theme is chosen

Browse Source 
<x-theme-toggle mode="contrast"> is the picker's row for M3's three levels, marking
the one in force so the operating system's setting shows while the choice is system.
The scheme picker's dots follow the level on screen instead of always promising the
standard colours, and the showcase's colour section puts the three levels side by
side — data-scheme beside data-contrast, the way a profile's level blocks key.
Plan: docs/plans/material-3-alignment.md, step 7 (core C2).

Every scheme is generated at M3's three contrast levels — standard, medium (3:1) and high (7:1) — and the
head script writes the visitor's to <code>&lt;html data-contrast&gt;</code>, following the operating system
until they choose. The page keeps its surface; the ink, the outlines and the containers carry the level.
