Add HIOKI channel range controls and live range display

Browse Source 
- GUI: voltage/current range selectors for Ch5 and Ch6 with AUTO option
- Worker: queries current V/I ranges each poll cycle, pushes to GUI
- Setting a fixed range automatically disables auto-range for that channel
- Live display shows current range values below each channel's readout
