feat(aigc): add auto-redirect when generation completes

Add complete event to GeneratingProgressPanel that emits when task status is completed and progress reaches 100%. Add handler in the parent progress page to automatically navigate to task detail page when the complete event is triggered, and stop ongoing task detail polling. Also enhance media download handling in the detail page with proper WeChat mini-program file path handling, error wrapping, temporary file cleanup, and improved error reporting for download failures.
