Summary

LiveButtonState.onClick() always seeked to the live point and played, even while an ad was playing. SeekBarState already disables the seek bar during ads. LiveButtonState now does the same:

val enabled: Boolean get() = !playingAd   // from player.ads.isPlaying

fun onClick() {
    if (!enabled) return
    ...
}

• playingAd is re-read on AD_BREAK_BEGIN, AD_SKIP and AD_BREAK_END, the same events SeekBarState uses.
• The mobile and TV LiveButton pass state.enabled to their button, so it's shown as disabled while an ad plays.
