Enhance media file resolution and improve StrokePanel functionality

[axif0]

Modernizes Quantum Brush's UI by replacing the old Java/Swing frames with a single React 19 + TypeScript + Zustand + Konva app (Control Panel, Canvas, Stroke Manager) running on Tauri 2 for desktop, with a Python HTTP fallback server for browser/web use, the original quantum logic in effect/apply_effect.py is untouched, so strokes still flow through the same pipeline as before; the MVP covers the full workflow (project create/open/import/draw/run/apply/export) plus a real deploy path (Vercel for the UI, Render for the API), and out of scope for now is the IQM hardware tab, undo/redo, and persistent storage on Render's free tier.

Hello, @axif0 , your GIF doesn't show the applied effect after each stroke execution, and the key features of quantum brush is not available on your app.

Also, if you are participating in UnitaryHACK, you must leave the comment on the main issue thread.

@artreadcode I fixed some issues. I also check that the using free render tier(takes too much time) is not suitable for running backend and update the gif checked by locally -

Can you please check.
