v0.4.25: add volume argument to /videoPlace, -1 mutes

New signature:
  /videoPlace <pos> <facing> <width> <height> <volume> <url>

volume is int -1..100. 0..100 sets percent and clears mute; -1 is a CLI
shortcut that sets muted=true (underlying volume kept at 0.5 so a later
/videoMute false restores audible level without re-typing). Matches the
percent scale shown in the config GUI.
