jimxie-oai 166aed9854 Preserve image generation failure metadata for premium usage limits (#57275) ...

## Why

Image generation usage-limit errors with the `imagegen_premium` limit ID were not recognized as structured `UsageLimitExceeded` failures.

## What changed

Recognize `imagegen_premium` alongside `image_gen`, preserving the limit ID and available reset time in image generation failure metadata.

## Testing

Extend app-server coverage to verify premium limit metadata and reset-time fallback in completion events, thread reads, and resumed threads. Add unit coverage for missing exhausted-window reset times and unrelated or absent limit IDs.
