- Fix sat_accounts.sql: split multi-row INSERT into individual statements
so parent_id subqueries resolve correctly (was producing all NULLs)
- Add tenant_config table to v1.0 schema (required by CFDI invoicing)
- Seed tenant_config with RFC/regimen during tenant provisioning
- Fix cancel_sale to pass complete sale data for accounting reversal
- Fix CFDI XML builder: use `or` instead of dict.get() defaults to
handle explicit None values from DB (clave_prod_serv, clave_unidad)
