fix: use capture phase and stopImmediatePropagation for ESC key handling

- Register keydown listener in capture phase (true) so Preview handler
  fires before any bubble-phase listeners (e.g. parent Dialog)
- Replace stopPropagation with stopImmediatePropagation to also block
  other capture-phase listeners registered after this one
