* feat(api): add amount_cents + signed_amount_cents to transactions * fix: use currency.minor_unit_conversion for amount_cents - Replace hardcoded *100 with currency.minor_unit_conversion - Handles JPY (0 decimals), KWD/BHD (3 decimals), etc. correctly - Add assert_amount_cents_fields helper to validate sign/scale invariants
