refactor(controllers): convert website_list_for_contact currency lookup to ORM

get_list_context built the enabled-currency symbol map with a raw
frappe.db.sql select. Convert to frappe.get_all (as_list). MariaDB-identical.

Adds a test asserting the currency-symbol map is built and contains a known
enabled currency, on both engines.
