fix(timer): address review findings on the group timer

- keep the pending and none phases when showing the group timer. These describe the
  playback state rather than a threshold, so collapsing them made roll standby render
  as a running countdown and silently dropped user styling keyed on the phase
- only show the group indicator for timer types which render the running timer. It was
  labelling the wall clock, and the invisible display of the none timer type, as a group
- accept useGroupTimer in the MCP group patch. It was documented in the group shape but
  dropped on write, which reported success without applying the change
- narrow the timer preview tooltip, which claimed all views follow the group timer when
  only the timer views do
