Mustool MT15/29: corrections and additions from cloud data

Issue #3209 had the log message from cloud fully describing some dps,
allowing Formaldehyde sensor scale and Alarm volume options to be clarified.

- cloud docs say scale is 3 (decimal places), which along with mg/m³ units
  means there should be no scaling needed with µg/m³ units
- cloud docs give the list of options for alarm volume so a select entity can
  be created for that.

Also range information from the app allows alarm threshold entities to
be created.
