Default flipped to off so voice doesn't get coloured by browser NS on
first run. Users turn it on explicitly under Settings → Sprache, where
the toggle already lived before the in-call button shipped.
The in-call SparklesIcon button and all the associated wiring
(onToggleNoiseSuppression, noiseSuppression prop, local subscription
in InCallPanel) is removed. The hot-swap UX is preserved: a new
subscribeAudioSettings watcher in CallContext detects noiseSuppression
flips during an active call and re-runs setupMicPipeline so the change
takes effect without rejoining.
