fix: prevent modal close when dragging from content to mask

- Use bubbling `onMouseDown` to track if the click originated from the mask.
- Only trigger close in `onClick` if both mousedown and click targets are the wrapper.
- Reset tracking refs when dialog becomes visible to prevent state pollution.
- Remove capture listeners to avoid potential event conflicts.
