Add configurable displayField to award definitions to control what
is shown in award details instead of always using the entity value.
## Award Definitions Updated
- DXCC: displayField = 'entity' (shows country name)
- DXCC CW: displayField = 'entity' (shows country name)
- WAS: displayField = 'state' (shows state name)
- VUCC: displayField = 'grid' (shows grid square)
- RS-44: displayField = 'callsign' (shows callsign)
## Backend Changes
- Preserve displayField when normalizing award rules
- Use displayField to determine entity name in details
- Fallback logic for awards without displayField
- Add satName to entity data for better display
This fixes VUCC showing grid squares instead of country names.
