perf: optimize Vite dev server startup

Added explicit optimizeDeps.include to pre-bundle common dependencies:
- React ecosystem (react, react-dom, react-router-dom)
- Icon libraries (@icons-pack/react-simple-icons, lucide-react)
- Other deps (date-fns, jszip, zustand, @tanstack/react-virtual)

Also added server.fs.allow config for monorepo file serving.

This should speed up subsequent dev server starts by ensuring these
dependencies are consistently pre-bundled.
