Patrik 751691aeaf fix(plugin-import-export): omit CSV columns when toCSV returns undefined (#12923 )

### What?

Ensure fields using a custom `toCSV` function that return `undefined`
are excluded from the exported CSV.

### Why?

Previously, when a `toCSV` function returned `undefined`, the field key
would still be added to the export row. This caused the column to appear
in the CSV output with an empty string value (`""`), leading to
unexpected results and failed assertions in tests expecting the field to
be truly omitted.

### How?

Updated the `flattenObject` utility to:
- Check if the value returned by a `toCSV` function is `undefined`
- Only assign the value to the export row if it is explicitly defined
- Applied this logic in all relevant paths (arrays, objects, primitives)

This change ensures that fields are only included in the CSV when a
meaningful value is returned.
