feat: animate local speaker ring from MoQ frame transmission

Wire the local user's avatar into the existing speaking-ring animation so the host/speaker sees the same green ring + amplitude glow on their own cell that remote speakers already get. Ground truth is the broadcaster's `publisher.send(opus)` success: the new `onLevel` callback fires only after a frame actually leaves on the wire, computed from the raw PCM peak (shared `peakAmplitude` util used by both the player decode loop and the broadcaster capture loop). This means the animation reflects what the relay sees, not any UI-side mute / role state that could be stale or buggy — if frames are flowing, the ring plays. Plumbing: `NestsSpeaker.startBroadcasting` gains an optional `onLevel` that the moq-lite + IETF broadcasters both honour, the reconnecting wrapper replays it on every session reissue (alongside the existing mute-intent replay), and `NestViewModel.startBroadcast` hands it a lambda that calls the existing `onSpeakerActivity` / `onAudioLevel` plumbing keyed on the local pubkey. The 250 ms speaking-timeout fades the ring naturally when the user mutes or stops broadcasting.
