Enhance CMS Entity with JSON Tags

- Added JSON tags to all fields in the CMS entity and its related sections (heroSection, chartSection, cardSection, contactSection, footerSection) to ensure proper serialization and deserialization in API responses.
- This change improves the API's usability by providing clear JSON representations of the CMS data structure.
