feat(web): Storybook for offline UI design + light theme + brand spinner

Stand up Storybook so the management console can be designed without a running
host, plus the design-system work that surfaced along the way.

Storybook (@storybook/react-vite):
- Slim Start/Nitro-free vite config; the preview imports the app's real
  src/styles.css directly so the design tokens stay single-sourced (no mirror).
- Stories for the @unom/ui primitives (Button/Card/Inputs/Badge), brand marks,
  the AppShell (throwaway in-memory TanStack router), and every data-driven page
  (Dashboard/Host/Clients/Library/Settings) rendered offline via a window.fetch
  stub + typed fixtures. The route page components are exported so stories can
  render them.

Light theme:
- styles.css now carries a light :root (lavender, from the docs palette) with the
  existing violet chrome moved to .dark; the live console still pins html.dark by
  default, so this only adds the option (Storybook's toolbar toggles it).
- Fixes a stray `*/` inside a comment that prematurely closed it and silently
  broke Tailwind's @theme processing.

Spinner:
- The punktfunk lens recreated with motion/react: two circles surge through one
  another in depth (JS perspective scale + z-index — robust where mix-blend-mode
  flattens CSS preserve-3d) with a screen-blend lens highlight. Replaces the
  skeleton loading state in QueryState; removes ui/skeleton.tsx.
