fix: Crash when editing column with only one defined min/max value (#897

)

**Fix crash due to undefined min/max values causing toFixed error**

When editing a column with only one defined min or max value, the app
would crash with the error "cannot read properties of undefined (reading
'toFixed')".
To resolve this, we updated the validation logic to allow undefined
values for min and max. This prevents the app from attempting to format
undefined values, eliminating the crash and allowing users to safely
edit columns with incomplete min/max values.
