test(workflows): raise beforeAll timeout for migration-heavy CRM suites

The workflow/dunning suites boot the full core-migration set in beforeAll via
bootCrmDb. In isolation that's ~1.3s, but under full-suite parallel load on a
small CI runner it can exceed Jest's 5s default, timing out beforeAll and
failing every test in the file (the CI flake). Match the existing pattern used
by the other migration-heavy CRM suites (discountLineItems, incomingInvoiceRebill)
and set jest.setTimeout(30000) on workflowEngine, workflowRoutes and
invoiceDunning.
