Updated account deletion process and refactor packages

The primary update was on the process of account deletion where email notifications are now sent to users. The @kit/emails was also renamed to @kit/email-templates and adjustments were accordingly made on the relevant code and configuration files. In addition, package interaction was refactored to enhance readability and ease of maintenance. Some minor alterations were made on the User Interface, and code comments were updated.
