feat: update version to 0.7.3 and enhance maturity model context bindings

- Incremented application version to 0.7.3 and updated database schema version to 20260427026.
- Enhanced maturity model context bindings with new hierarchical resolution logic for focus areas, style directions, and training types.
- Added new API endpoints for managing maturity model context bindings.
- Updated frontend components to support the new context binding functionality and improved admin UI for better user experience.
- Documented changes in the changelog for version 0.7.3, including new features and improvements.
