User report: lowering Max Crop Res caused the crop window to miss the
detected object. Root cause: the contract-around-center logic in
_crop_image_by_mask works fine for centered bboxes but pushes the crop
window away from the bbox when the bbox is near an image edge (e.g., a face
touching the right edge of a 512-wide image with max=200 produces a crop
centered at x=296 which only partially overlaps the actual face at x>=300).
Fix per user suggestion:
- Remove min_crop_resolution + max_crop_resolution from Builder UI
- Defaults are now no-op (min=0, max=99999)
- Florence2's polygon + grow_expand + crop_padding fully determine crop region
- Python helper keeps the params for backwards compat with existing tests
