Add `validationDivision` errors in UI

[kungfooman]

Fixes: #147

The division errors in UI looks like this:

If there is more context available, we use it:

function test() {
  console.log("ret", 123 / 0);
}
test();

The name row doesn't make too much sense - it's an artifact of only checking function arguments from the beginning and a division isn't exactly a function with argument names (I guess we could call it dividor in case of 123 / 0, but we also check for bigint/number incompatibility e.g.)
