ui/simplelistpage: use Component type for createForm

[Forfold]

In a PR (#2434) converting a Dialog component to Typescript rendered as a child of SimpleListPage component was forced to set the onClose prop to optional, because in SimpleListPage we clone the passed Dialog component and then append the onClose property to props.

We should think about setting onClose to required for our Dialog components, which would require SimpleListPage to accept a Component instead of a JSX.Element.

E.g.

<SimpleListPage
  createForm={<RotationCreateDialog />}
/>

would change to

<SimpleListPage
  createDialogComponent={RotationCreateDialog}
/>

and we could add a render prop option, too, if some components need to pull off some shenanigans in scope as well:

<SimpleListPage
  renderCreateDialog={(props) => <RotationCreateDialog foo={bar} {...props} />}
/>
