v1.0.14: Display blanking config in captive portal
- Add Options section to captive portal with display blanking dropdown
- Options: Never, 1, 5, 10, 30, 60 minutes
- Change EEPROM blanking value from seconds to minutes (supports up to 255 min)
- Update Display.h and Utilities.h to interpret stored value as minutes
- Default blanking timeout changed from 15s to 1 minute
