Fix scale-selection 500 error (missing BytesIO import) and compact GPU badge

ai_tools.py: add 'from io import BytesIO' — scale_selection and paste
endpoints used BytesIO directly but it was only imported locally in one
unrelated function, causing NameError on every scale call.

provider-badge.js: redesign badge to fit the narrow (~40px) left toolbar.
Was rendering 'GPU · sdxl_offload · Quadro RTX 3000' inline which wrapped
into multiple lines covering tool icons. Now shows a status dot + short
label (SDXL / OAI / Rep…) with all details moved to the hover tooltip.
