- Tests caught 2 real bugs:
- Zod NaN bypass in orders/offers schemas (Number(v) || fallback)
- invoiceTotalWithVat using Number() on { toNumber() } objects
- 7 new test files covering auth, env, exchange rates, NAS paths,
schema NaN rejection, invoice VAT calculation, customer validation
- 45 tests passing, build clean
