* docs(sync): document foreign key resolvers (#495)

Adds a new "Foreign key resolvers" section to the Sync API guide
covering the {resolver, value, nullOnMissing} payload shape and
listing the eight built-in resolvers (product.number plus the seven
new tier-1 resolvers for currency, locale, payment_method,
shipping_method, document_type, salutation, tax).

Includes a warning about tax.tax_rate's non-unique column behavior.
