Fix network device description/machinenotes display and edit

- Fix ADO cursor issue where reading rs("description") twice caused
  empty values (IsNull check consumed the field value)
- Change all device pages to read description field once using
  `description = rs("description") & ""` pattern
- Add deviceDescription variable in displaydevice.asp
- Fix machinetypeid mapping: IDF=17, Camera=18 (was swapped)
- Add model dropdown fix to include currently assigned model
- Add server application tracking feature
- Various other improvements and fixes

Files affected:
- displaydevice.asp, displaylocationdevice.asp
- deviceaccesspoint.asp, deviceserver.asp, deviceswitch.asp
- devicecamera.asp, deviceidf.asp
- savenetworkdevice.asp, networkdevices.asp
