The simulator now shows the full source image with a draggable crop
window overlay. Drag the frame over the photo to position the crop —
dimmed regions show what gets cut. The dithered e-paper preview renders
live in the side panel.
Mode toggle: "Fill" (zoom with draggable pan) vs "Fit" (letterbox).
Save persists per-image settings used when the ESP32 fetches the photo.
