feat(cms): enhance content editors and implement automatic ID generation

Improve the CMS administration interface across multiple pages (Accreditation, Admissions, History, Partnerships, and Policies) with a focus on usability and data integrity.
Key changes include:
- Implement `ensureUniqueIds` utility to automatically generate and maintain unique slugs for content items, removing the need for manual ID entry in the UI.
- Refactor the Admissions calculator to support detailed per-option editing via a new dedicated view and routes.
- Replace basic datalists with a custom, searchable icon combobox component for better visual selection.
- Update `_renderSingletonPageView` to handle active tab persistence via query parameters.
- Streamline editor configurations by removing redundant fields and improving help text.
- Enhance the Admissions "Key Dates" editor with a dynamic table interface for managing columns and rows.
- Normalize data payloads in controllers to ensure consistent API responses and internal linking.
