MiniMax already had entries in the music/audio/video registries, but no entry at all in imageRegistry.ts and no dedicated provider handler under open-sse/handlers/imageGeneration/providers/. A MiniMax image-model request therefore fell through the format dispatch in imageGeneration.ts to a 404/unmatched-format response instead of reaching MiniMax's synchronous image_generation endpoint.
Registers a minimax image provider (format: minimax-image, models image-01/image-01-live) and a new handleMinimaxImageGeneration handler that POSTs to https://api.minimax.io/v1/image_generation and normalizes data.image_urls into the OpenAI-compatible images payload.
