New Features
- Selectable Modbus address space (5-digit / 6-digit) — a new Address Space selector in the Display Definition and Address Scan dialogs, backed by a reusable
AddressSpaceComboBox. Address and length ranges now follow the selected space (1…9999 vs 1…65536) instead of always using the full 16-bit range. - Configurable hex view buttons — a Show Hex View Buttons option in Display Definition toggles the hex buttons on the address, slave ID and length fields across all Modbus dialogs (Display Definition, Address Scan, Mask Write Register, Write Coil/Holding Register, Preset Data). Disabling it also clears any active hex view; per-field hex state is now persisted with the display definition.
