fix(desktop): extract wake pause into a callback to satisfy the no-ref-mirror lint rule

The wake-pause effect assigned wakePausedRef.current inside useEffect,
tripping eslint's no-restricted-syntax guard against atom→ref mirroring.
The ref is actually a request token (did WE issue wake.pause?), not a
reactive mirror — moving the assignment into a pauseWakeForVoice
callback keeps the semantics and passes the rule without a disable.
