fix: replace imperative DOM listener with React synthetic event for resize-handle double-click

The aspect-fit double-click feature broke after manual resize because imperative
DOM listeners (useEffect + addEventListener) fall out of sync when React Flow
re-renders resize controls. Switches to a React onDoubleClick handler on a
`display: contents` wrapper, which stays in sync across all re-renders.
