Refactor CookieBanner and Contact API for improved functionality and security

- Removed localStorage fallback from CookieBanner, simplifying consent management.
- Refactored manual review email handling in the Contact API to utilize HTML templates for better structure and security.
- Enhanced email content generation by escaping HTML special characters and using template files for dynamic data insertion.
