Add Group and Aux master actions, feedbacks and preset sections

Groups were only reachable through the generic "Buss:" actions, whose
dropdown mixes all 25 busses, so users could not find group fader
control.

- New "Group:" and "Aux master:" mute, solo, set fader (with fade time)
  and adjust fader actions; their dropdowns list only busses of that
  type. Matching muted, solo, fader text/position, meter, signal and
  peak feedbacks.
- The old buss_* actions and feedbacks keep working for existing
  buttons and are now labelled "Any buss (aux or group)".
- Presets: "Busses" is split into "Groups" and "Aux masters", and the
  bus meters into "Group meters" and "Aux meters". A bus that changes
  type on the console moves section on the next rebuild.

npm test: 542 checks pass on Node 25 and on Companion's Node 22.
