Lets callers drive Bar/Radial/Grid/Wave/Aura visualizers with precomputed volume data instead of live useMultibandTrackVolume/useTrackVolume output, while preserving existing state/track visibility gates. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

Bar/Radial/Grid now trim excess values or pad by duplicating the last value when a supplied volumeBands array doesn't match the expected count. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Replace volumeBands (number[]) with a scalar volume prop on Wave/Aura, since they only ever needed one value. Drops the now-unused resolveVolumeFromBands averaging helper. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Bar/Grid never gated on audioTrack, only Radial did, which silently zeroed out an explicitly-provided volumeBands override whenever no live track was connected. Also adds Storybook demos (with a shared simulated speech-waveform generator) showing the volumeBands/volume override for all 5 agents-ui visualizers.

Issue
Related to https://github.com/livekit/web/pull/4377
The demo's on livekit.com/products/agents-ui require simulated audio.
We don't have a mechanism for providing an audioTrack, so the components needed to be forked.
This complicates updates and maintenance.
Overview
Adds override props to the
agents-uiaudio visualizer components,letting callers provide precomputed volume data overriding the live audio hooks.
