style(cms): improve editor ui and implement collapsible item cards

Enhance the CMS administration interface by introducing a more refined design system for content editors. This update replaces generic Bootstrap utility classes with dedicated CMS styling to improve visual hierarchy and usability.
Key changes:
- Introduce `cms-editor-group` and `cms-item-card` classes for consistent grouping and item styling.
- Implement collapsible functionality for item cards to manage long lists of content more effectively.
- Standardize editor buttons, including new styles for drag handles, remove buttons, and add buttons.
- Update the fixed bottom action bar with improved backdrop filters, shadows, and spacing.
- Refactor editor scripts across Accreditation, Admissions, History, Partnerships, and Policies to utilize the new UI components and collapse logic.
- Add comprehensive CSS to `main.ejs` to support the new CMS design tokens and layout behaviors.
