Improve debugging capabilities for OAuth flow in elicitation callback:
- Add detailed logging for consent screen handling
- Capture screenshots when consent screen not detected or fails
- Replace networkidle wait with explicit callback URL polling
- Add 2-second grace period for server-side callback processing
- Log page title and current URL for debugging
This helps diagnose issues like expired OAuth clients or authorization failures during real elicitation testing.
