feat(ui): migrate all view bodies to design tokens (F1b)

Tokenize every remaining component <style> — calculator, order tab,
inspectors, tables, report sections, lobby, auth, mail, battle viewer,
toasts, map overlays. A scripted pass handled the unambiguous core
palette (text/bg/surface/border/accent/danger/muted), the rest were
mapped to the semantic/grey tokens by role.

Remaining colour literals are the documented exceptions only: the
battle-scene SVG data-visualisation palette (fixed dark, like the WebGL
map canvas), overlay scrims (modal / map-canvas), and directional or
deliberate drop shadows. The default theme stays dark until light
coherence is signed off across the views.

Updates ui/docs/design-system.md (migration status + exceptions).
