During HMR, `recreateLView()` destroys the old LView and removes its
DOM nodes, but never cleans up dehydrated view DOM nodes stored in
`LContainer[DEHYDRATED_VIEWS]`. These are SSR-rendered DOM nodes
preserved by Angular's hydration system. When the new view renders,
both the old dehydrated DOM and the new DOM coexist, causing visible
duplication (e.g. `<app-shell>` header/footer appearing twice).
Call `cleanupLView` from the hydration cleanup module after
`destroyLView` and before `removeViewFromDOM` to remove any remaining
dehydrated DOM nodes before the replacement view is rendered.
Fixes #66503
