Code-splits the module into "dnd.js", reducing the ui.js bundle size. This module is only needed when viewing lists.
## Room for improvement
`ClaimList` can probably improve further by only using the dnd components in "edit" mode.
## Implementation notes
- The modules are not default exports, so the additional chaining to `React.lazy` was required.
- Experimenting with using an Object to store the import so that a single "prettier-ignore" can be used to make it not wrap.
- The FlowFixMe came from the original code. It is unclear why it is needed to resolve the module, but Haffa mentioned it's something related to .flowconfig.
