- Introduced a new template for listing scenarios associated with a project. - Added metrics for total, active, draft, and archived scenarios. - Implemented quick actions for creating new scenarios and reviewing project overview. - Enhanced navigation with breadcrumbs for better user experience. refactor: update Opex and Profitability templates for consistency - Changed titles and button labels for clarity in Opex and Profitability templates. - Updated form IDs and action URLs for better alignment with new naming conventions. - Improved navigation links to include scenario and project overviews. test: add integration tests for Opex calculations - Created new tests for Opex calculation HTML and JSON flows. - Validated successful calculations and ensured correct data persistence. - Implemented tests for currency mismatch and unsupported frequency scenarios. test: enhance project and scenario route tests - Added tests to verify scenario list rendering and calculator shortcuts. - Ensured scenario detail pages link back to the portfolio correctly. - Validated project detail pages show associated scenarios accurately.
