feat(cms): implement structured tuition data normalization and editor

Refactor tuition data from a simple numeric array to a structured object
containing time labels and values. This allows for more flexible
charting and precise data entry in the CMS.
- Add `normalizeTuition`, `normalizeTuitionSeries`, and `normalizeTuitionPoint` to `admissionsController.js`
- Update `admissionsConfig.js` to use `objectList` for tuition data points instead of `stringList`
- Migrate existing tuition data in `admissions.json` to the new structured format
- Fix duplicate text in `admissions.json` grant amounts and descriptions
