Upload an image (signed)
Upload raw image bytes (multipart/form-data) using a short-lived, single-use token minted via the bloom_create_image_upload_url MCP tool. The token in the path is the credential — no Authorization header is expected. Same validation/storage pipeline as POST /images/uploads/file. Returns an image ID and URL usable with the generate or edit endpoints.
