fix(cat): align Andromeda panel mapping with real G2 hardware (Thetis)

Button/encoder indices follow Thetis MakeNewAndromedaDataset (our 0-based
index = Thetis Number - 1), verified against andromeda_test/AndDecode.pas.
The old map assumed sequential 0,1,2.. and truncated at 32; the real panel
sends sparse indices up to 47.

- AndromedaMap: AND_MAX_BUTTONS 32->48, renumbered button/encoder tables;
  new actions abVFOAtoB/abVFOBtoA/abVFOLock/abStartStop/abShift.
- RadioController: VFO Lock (FVfoLock, rfVfoLock, SetVfoLock, gate in
  TuneActiveBy).
- AndromedaPanel: wire A>B/B>A/SDR-ON/Lock; Shift band-keypad layer
  (#28 latch, #29..39 -> SetBand 160m..6m, non-sticky); aiVFOLock/aiShift
  indicators.
- Filter High/Low (#4/#5) left as width approximation per decision.
- doc/ANDROMEDA.md updated.
