feat: stream gpt-image generation via SSE with keepalive

Browse Source 
- /api/generate now responds with text/event-stream end-to-end
- forwards upstream image_generation.* / image_edit.* partial+completed events
- 20s keepalive comments survive Cloudflare's 120s proxy-read timeout
- falls back to non-streaming when upstream rejects stream/partial_images
- drops @ai-sdk/openai-compatible, @ai-sdk/react, ai (unused)
- frontend consumes SSE via fetch+ReadableStream, shows progressive preview
