Move all web dashboard dependencies from web/package.json into root:
- React 19 + React Router 7
- Radix UI components (14 packages)
- Tailwind CSS v4 + bun-plugin-tailwind
- Recharts, React Hook Form, Zod validation
- Dev dependencies: @types/react, @types/react-dom, tailwindcss
This fixes a production issue where web dependencies weren't being
installed in Dockerfile.prod, even though bot/index.ts imports from
web/src/server at runtime.
VPS deployments using Dockerfile.prod will now have all required
dependencies in a single node_modules.
