The billing schema has been revamped to allow more flexible billing setups, supporting multiple line items per plan. Changes extend to related app and UI components for a seamless experience. As a result, the previously used 'line-items-mapper.ts' is no longer needed and has been removed.
This commit removes sensitive data including keys, URLs, email, and other configurations from the .env.production file in the web app. Moving forward, the file will only contain public variables, enhancing the overall application's security.
