Lifts the `state.kind === 'connected'` guard from the soundboard hotkey
useEffect so OS-level shortcuts are always registered. Inside a call the
existing `playSoundboard` path routes audio into the LiveKit pipeline so
peers hear; outside a call the new `playSoundboardLocal` helper fetches
the blob via `getSoundBlob`, creates a short-lived object URL, and plays
through a fresh HTMLAudioElement on the system default output.
