feat(cms): enhance content editors with dynamic UI configs and validation

Implement a more flexible, configuration-driven approach for CMS editors across accreditation, admissions, and partnerships modules.
- Move UI labels, help texts, and field limits from hardcoded views to `editorUi` configurations in config files.
- Add server-side and client-side validation to prevent duplicate category tabs in accreditation and partnerships editors.
- Refactor partnership and admission views to dynamically render tabs and fields based on the provided configuration.
- Update field length constraints and default values across multiple content editors to better align with frontend requirements.
- Improve the admissions calculator editor with dynamic field configurations and default value fallbacks.
