Split off from T405791: New batch data entry update: link to contacts in import results + show names.

Ideally, instead of displaying the contact id, we would display the contact display name with a link to the contact. This will require a FK be created from the import table to the contact (or other relevant entity).

Similarly, we would display the soft credit type name (or other pseudoconstants from joined tables). See this upstream PR for why this can't be handled in the way the non-joined ones are handled.
