fix(ui): race condition with gallery search

It was possible to clear the search term while a debounced setSearchTerm is still pending. This resulted in the gallery getting out of sync w/ the search term.

To fix this, we need to lift the state up a bit and  cancel any pending debounced setSearchTerm calls when closing the search or clearing the search term box.
