get_payer_address_html picks one company address with ORDER BY (Postal DESC, Billing DESC)
LIMIT 1 and no column tie-break. When a company has two addresses of the same address_type
the two CASE keys tie, so the LIMIT-1 row is implementation-defined and MariaDB and PostgreSQL
can return a different address.name — i.e. a different payer address on the rendered IRS-1099
form for identical data.
Add a final .orderby(address.name), mirroring the sibling get_street_address_html in the same
file (which already carries the "deterministic LIMIT-1 tie-break across engines" order). The
pick is now the lexicographically-smallest name on both engines.
