Patrik 335af1b8c9 fix(plugin-import-export): preview table to include all selected columns regardless of populated data (#12985 )

### What?

Ensure the export preview table includes all field keys as columns, even
if those fields are not populated in any of the returned documents.

### Why?

Previously, if none of the documents in the preview result had a value
for a given field, that column would be missing entirely from the
preview table.

### How?

- Introduced a `getFlattenedFieldKeys` utility that recursively extracts
all missing flattened field accessors from the collection’s config that
are undefined

- Updates the preview UI logic to build columns from all flattened keys,
not just the first document
