Description
On a layer with a numeric primary key, QGIS enforces a not null constraint.
We may expect to circumvent this constraint with a default value. With the default "Range" widget however, the default value is not taken into account and there is no way to validate the form without manually entering a non null value.
However with the "Text Edit" widget, the default value is correctly taken.

Fix "Allow null" in range widget (fixes #20831)
By default a range widget is built with a minimum value set to the
minimal integer that is possible to represent. When "allow null" is
enabled, a new value (minvalue - 1) is inserted. With the default
value, we then had an integer overflow.
