acp_thread: Clear running_turn when prompt task drops tx (#55562)

`AcpThread::status` is purely `running_turn.is_some()`. The cleanup that
takes `running_turn` sat below the early-return guard that fires when
the prompt response oneshot resolves to `Err(Cancelled)` (the inner
`send_task` was dropped before `tx.send`). Any code path that drops the
in-flight `send_task` therefore left the panel stuck in `Generating`.
Reordered so cleanup runs before the dropped-tx guard; the same-turn
invariant is preserved.

Related to #47928 (partial — that issue also has an upstream
`claude-agent-acp` component this PR does not address).
