🐛(frontend) optimize mute-all to skip participants without mic tracks

Improve mute-all functionality by filtering out participants who are
already muted or lack microphone publishing permissions, and ignore

Prevents unnecessary mute operations on participants who cannot be
muted, prevent API errors.
