- Updated form template to prefill currency input with default value and added help text for clarity. - Modified integration tests to assert more descriptive error messages for invalid currency codes. - Introduced new tests for currency normalization and validation in various scenarios, including imports and exports. - Added comprehensive tests for pricing calculations, ensuring defaults are respected and overrides function correctly. - Implemented unit tests for pricing settings repository, ensuring CRUD operations and default settings are handled properly. - Enhanced scenario pricing evaluation tests to validate currency handling and metadata defaults. - Added simulation tests to ensure Monte Carlo runs are accurate and handle various distribution scenarios.
