Add workflow_id to all websocket messages

This commit addresses BE-672 by ensuring all execution-related websocket
messages include the workflow_id field when available.

Changes:
- Added extract_workflow_id() helper function in comfy_execution/jobs.py
  to extract workflow_id from extra_data
- Updated execution.py to include workflow_id in all websocket messages:
  - execution_start
  - execution_cached
  - execution_success
  - execution_error
  - execution_interrupted
  - executing
  - executed (including cached UI)
- Updated main.py to include workflow_id in:
  - progress messages (via hijack_progress hook)
  - final executing message (node=None)
- Updated comfy_execution/progress.py to include workflow_id in:
  - progress_state messages
  - preview image metadata

The workflow_id is extracted from extra_data['extra_pnginfo']['workflow']['id']
and is conditionally included in messages only when present, maintaining
backward compatibility with workflows that don't have this field.

Fixes: BE-672
