DEN-8693: Support for the disinfect
- Adding support for reading the brightness value from the Linux file system instead of having another file just to keep the same value.
- Fixed a bug in the Active Alarm List request.
- Adding the functionality of the Alarm Volume.
- Modified the Disinfection screens[Heat/chem] check marks with the new bundled states provided by FW for UI and the flush states are yet to come.
- Adjusted the Active Alarm List screen a little to be able to show all the current Alarm messages without cropping.
