Input sanitization missing for config "Decimal Shift"

[torwag]

The config to shift the decimal point (Decimal Shift) after recognition of all digits, expects the number of digits to move the decimal point. E.g. 1376 l are 1.376 m3 thus -3 digits.

Obvious my overtired engineer brain did what it always does and divided by 1000 and as this, I entered 1000 into that field.

As a side effect that seems to expose a missing input sanitization. The ESP simply silently crashes. It might be a good idea to limit inputs between -9 and 9 as everything else seems rather unlikely.

this is an issue we have with almost any input parameters
