feat: add Shaman totem frame with element-colored duration bars

- Renders below pet frame, visible only for Shaman (class 7)
- Shows each active totem (Earth/Fire/Water/Air) with its spell name
  and a colored countdown progress bar
- Colored element dot (brown/red/blue/light-blue) identifies element
- Only rendered when at least one totem is active
