Fix supply voltage display: correct constant per board type, hide on unsupported boards

Browse Source 
Per Appendix A of openHPSDR Ethernet Protocol v4.3:
- Boards 1,2,3 (Hermes/Angelia): V = ADC/4095 * 3.3 (was always using this)
- Boards 4,5 (Orion/Orion MkII): V = ADC/4095 * 5.0 (was wrong, showing ~66% of real value)
- Board 0 (Atlas) has no supply voltage measurement per protocol spec
  ("not Atlas bus systems")
- Boards 6 (Hermes Lite), 10 (Saturn): constant not documented, hide Supply field

ADCToSupplyVolts now takes BoardType and returns -1.0 for unsupported boards.
DoUpdateStatus omits the Supply field when -1.0 is returned.
