Replace frontend with deployed TS version from a08dd73
- Restore TS frontend source (canvas, tools, CRDT, components, services) - Keep 5 JSX components that TS code depends on (CADCanvas, LayerPanel, BlockLibrary, PluginRegistry, Toolbar) - Keep JS services (api.js, blockService.js) that components depend on - Fix vite/plugin-react version mismatch (downgrade to v4 for vite 6) - Add axios dependency - Skip tsc in build script (vite/esbuild handles transpilation) - Fix index.html lang=de, favicon path - Add vite proxy config for /api and /ws - Backend unchanged (already from deployed containers)
