feat(sync): synchronize customer addresses

Mirror the addresses embedded in GET /customer/🆔 per customer, delete
the ones missing from Hiboutik, then upsert each of them (failures logged
and skipped). CustomerAddress gains its own recipient (firstName,
lastName, company, phone) plus state and other.
