feat(cms): enhance policy editor with fullscreen mode and date picking

Improve the policy content management experience by adding a dedicated fullscreen editing mode and a structured date picker for effective dates.
- Implement fullscreen toggle in `policies-block-editor.js` with corresponding CSS for an expanded workspace
- Add `date` field type to `sharedFields.js` and integrate it into `policiesConfig.js`
- Implement date parsing and formatting utilities in `editor-script.ejs` to handle "Effective Date" strings
- Update `policiesController.js` to use `updateOne` for more reliable document persistence and state reloading
- Add support for `ICON_OPTIONS` in the policy editor configuration
- Refine editor UI layout and overflow handling for better stability with long content strings
