Customer/supplier type inference flagged any identity number whose digit
count was not exactly 10 as a foreign org number, so a 12-digit
century-prefixed personnummer (e.g. 19700616-7113) was misclassified as
non_eu_business instead of swedish_business — applying export VAT to a
domestic party. Recognize both 10- and 12-digit (19xx/20xx) Swedish numbers
via a new looksLikeSwedishIdNumber helper.
Separately, mapCustomer always wrote the provider's single identity-number
field into org_number, even for individuals. The customer form renders
personal_number for individuals (org_number for businesses), so a
Privatperson's personnummer was stored in a column the UI hides. Route the
number to personal_number for individuals.
Adds entity-mapper-customer-type unit tests.
