Claude 85f05e999c fix(client): make the screenshare volume slider actually change volume ...

Three defects made the screenshare tile's volume slider ineffective:

- The 0-200 slider mapped to element volume /200 clamped to [0,1], while
  the element attached at 1.0 — dragging the upper half did nothing. The
  screenshare slider is now 0-100 with 100 = 1.0 (HTMLAudioElement.volume
  cannot exceed 1.0; mic tiles keep the 0-200 boost range via LiveKit's
  GainNode-backed setVolume).
- Setting a volume before the screenshare audio track attached was silently
  dropped. The per-user volume now persists independently of the element
  map and is applied on attach.
- Changing the master output volume overwrote per-user screenshare volumes
  with just the master multiplier; they now scale together.

The slider and mute button also initialize from persisted state when a tile
is rebuilt, and unmuting via the button re-applies the restored volume.

Fixes #121
