Jan-Henrik Bruhn 0dfc8b731b feature: Implement Web Worker-based pattern conversion with progress tracking
Move Pyodide/PyStitch pattern conversion to a dedicated Web Worker for
non-blocking UI performance. Pyodide now loads in the background on app
startup with real-time progress indicator showing download and initialization
status.

Key changes:
- Create patternConverter.worker.ts with full PES to PEN conversion logic
- Add patternConverterClient.ts singleton for worker management
- Implement progress tracking (0-100%) with step descriptions
- Add inline progress bar in FileUpload component with contextual messaging
- Configure COEP headers for Electron to support Web Workers
- Pass dynamic asset URLs to worker for file:// protocol support
- Update UIStore with progress state management
- Simplify pystitchConverter.ts to delegate to worker client

Benefits:
- Truly non-blocking UI (heavy Python/WASM runs off main thread)
- Real progress feedback during 15MB Pyodide download
- Works in both browser and Electron (dev and production)
- Faster app startup perception with background loading
- Better UX with "waiting" state if user clicks before ready
