feat(navigation): Enhance navigation links and add legacy route redirects

- Updated navigation links in `init_db.py` to include href overrides and parent slugs for profitability, opex, and capex planners.
- Modified `NavigationService` to handle child links and href overrides, ensuring proper routing when context is missing.
- Adjusted scenario detail and list templates to use new route names for opex and capex forms, with legacy fallbacks.
- Introduced integration tests for legacy calculation routes to ensure proper redirection and error handling.
- Added tests for navigation sidebar to validate role-based access and link visibility.
- Enhanced navigation sidebar tests to include calculation links and contextual URLs based on project and scenario IDs.
