Will Miao 30b01b8a92 fix(recipes): offload EXIF to thread pool, throttle concurrent imports, eliminate duplicate Civitai API call ...

- Wrap ExifUtils.extract_image_metadata() with asyncio.to_thread() in
  both import handlers and analysis_service to prevent Pillow/piexif
  from blocking ComfyUI's event loop during batch imports.
- Add asyncio.Semaphore(2) to import_remote_recipe and import_from_url
  endpoints to cap concurrent heavy work and prevent event loop starvation.
- Pre-fetch Civitai image_info during download and pass it to the recipe
  enricher, eliminating a redundant get_image_info() API round-trip.
