The table update/duplicate steps awaited waitForDatabaseToLoad (a
public-infinite_tables waitForResponse) registered right after the mutation —
the same too-late-listener race that flaked the schema-visualizer test under
TanStack's faster render. The toBeVisible assertion immediately after each one
already waits for the list to refetch, so the waits are redundant. Removes
both and the now-unused import. Verified locally (x2) against the TanStack build.
