Add a feedback for every controllable state, matrix send presets

A matrix-send knob looked dead on the booth Companion although the console
followed it (verified through Companion's rotate API: -90 -> -60 -> -59):
the module had matrix send actions but no matrix send feedbacks.

- Every action with a readable state now has a matching feedback: matrix
  send on/level text/level bar, matrix and control group solo and fader
  bars, graphic EQ in and band gain text/bar, aux send pan text, and value
  text for trim, gain and filter frequencies. A test checks the parity.
- New action: matrix output solo.
- Matrix sends use the console's -90 dB floor: adjusting down from -inf no
  longer writes -150 there.
- Presets: "Matrix sends to <output>" (on/off and knob per matrix input)
  and graphic EQ in/out. 2970 presets, 1.8 MB.

npm test: 368 checks pass on Node 25 and on Companion's Node 22.
