Implement fwiz dashboard Command

[fotopixel]

As a developer debugging a Module Federation application,
I want fwiz dashboard to launch a visual overview of the federation graph and runtime state,
so that I can quickly understand which versions are loaded and where conflicts occur.

Acceptance Criteria

• fwiz dashboard starts a local Vite + React app (default port 5000).
• Graph visualization using react-flow showing hosts, remotes, and shared dependencies.
• Live runtime data via MF 2.0 plugin (loaded versions, share scope status).
• Clickable nodes show detailed info (version, load time, exposed modules).
• Responsive design with dark mode.
• Export graph as PNG/JSON.
