fix(424): add throttled field to all StoryAgent ctors and handle HardBlock in ws.rs

The initial commit added the `throttled` field to `StoryAgent` but missed
several construction sites in lifecycle.rs, test_helpers.rs, and scan.rs.
Also adds the `HardBlock` match arm in the WebSocket event conversion and
minor CSS/import ordering fixes.
