Async Job Behavior

This endpoint creates an asynchronous job. It immediately returns a job_id, and actual effect generation occurs in the background.

Polling Method:

1. Save the job_id received in the response
2. Poll GET /public/v1/job/{job_id} to check status
3. When status becomes Succeed, check results in image_urls

Status Flow: Pending → Succeed or Failed
