gsxdsm cf80622875 FN-5993: prevent PR metadata generation hangs

Bound PR AI metadata generation so the PR dialog falls back cleanly instead of hanging indefinitely.

- add a 60s timeout and abort-aware fallback path to dashboard PR metadata generation
- forward request abort signals from the PR metadata route and avoid writing responses after disconnects
- cover timeout/abort behavior in PR metadata generator and route tests
- document the bounded fallback behavior in the dashboard guide
