- Add upload progress bar (role=progressbar) with aria labels and size/MIME
validation before accepting the image preview.
- Surface validation errors inline (role=alert, data-testid=image-upload-error).

useV2 toggle, flood-risk select, collapsible sections) that drives the
new AVM v2 result card.
