/**
 * invoices.service billing-entity integration tests.
 *
 * Covers:
 *  - createInvoice with billingEntity=client snapshots clientName from client.fullName
 *  - createInvoice with billingEntity=company snapshots clientName from company.name
 *  - createInvoice throws ValidationError when client does not exist
 *  - createInvoice throws ValidationError when company is in another tenant (cross-tenant)
 *  - createInvoice uses entity primary email + address when none provided
 *  - createInvoice allows caller to override billingEmail and billingAddress
 *
 * Uses dynamic imports (PR 8 pattern) so env is loaded before service modules
 * touch `db`.
