Drop the react import nothing calls

useEffectEvent was named in eleven files that never call it. Ten were in
radix-ui alone, against a base-ui copy that upstream keeps byte-identical
to it, so an unused name was the entire difference between the two; the
eleventh, toc/index.tsx, carried it in both. Restoring the ten from
base-ui makes each pair identical again.

The symbol is real and React 19.2 exports it -- it is used, twice, in
thirteen other files. These eleven just never reached for it.
