test: add API route tests for 10 critical endpoints
Add test coverage for invoices, transactions, bookkeeping, and supplier invoice API routes. Includes test helpers (createMockRequest, parseJsonResponse, createMockRouteParams, createQueuedMockSupabase) and fixture factories (makeInvoice, makeCustomer, makeSupplier, makeSupplierInvoice, makeCompanySettings).
