Fix race condition: disable generate during preprocess, use preprocessed image, thread-safe progress

Use local RMBG model, fix device placement, improve tqdm progress tracking

Fix device mismatch, use remote RMBG client, improve progress tracking, translate comments to English

refactor: use remote BRIA-RMBG-2.0 for background removal (no local GPU needed)

fix: add @spaces.GPU decorator to preprocess for ZeroGPU compatibility

feat: add clear button, SSE progress tracking, multi-session support

UI updates: Pixal3D V1.1 branding, camera settings, readme, ref thumbnail, GPU duration 240s, fix EXR path
