[style](trx-frontend-http): refine web UI design system and a11y

Introduce a shared design-token layer and apply it to the web
frontend for a more consistent, readable, and accessible feel.
Pure CSS plus one HTML block; no app.js behaviour changes, and the
existing multi-theme (style x light/dark) system is preserved.

- Add spacing, type, radius and motion tokens to :root.
- Fix undefined --surface consumed by .controls-tray, which dropped
  the panel background entirely; it now resolves per theme.
- Set body line-height and font smoothing; collapse near-duplicate
  font sizes onto canonical scale steps.
- Rebuild the auth gate with classes and replace hardcoded colours
  (#ff6b6b, #9aa4b5) with theme variables so it renders correctly in
  every theme.
- Add an opacity fade on tab switches, gated by prefers-reduced-motion.
- Extend focus-visible rings to the spectrum canvas, tabindex controls
  and links.
- Add a self-theming --accent-text token to lift accent-coloured text
  (links, active tab) to WCAG AA without altering brand fills.
