The rest of the product reads the contact company from
additional_attributes[:company_name] (Contact.order_on_company_name scope,
ContactInfo.vue, ContactForm.vue, ContactSortMenu, widget contacts store).
DataImport::ContactManager was writing to additional_attributes[:company]
instead, so imported values silently never appeared in the Company field.
- Write to additional_attributes[:company_name]
- Accept either `company` or `company_name` CSV columns so existing
import templates keep working (`company_name` wins when both are set).
- Update the existing specs to assert against company_name and add a
new spec that verifies the company_name CSV column path.
Closes#14096
Revives the never-fully-resolved #9907.
