Prevent null values for BLE measured power, also allow negative values in case entire field is cleared out

[dshokouhi]

Summary

Fixes the following sentry error by defaulting to the correct value instead of crashing. I also noticed if a user clears out the field they can no longer add back a negative number so changed the field only for this setting as its the only one that expects a default value.
