feat(auth): support multiple root admin emails and enhance admin login verification

- Updated the environment variable configuration to allow multiple root admin emails via `ADMIN_EMAILS`, while maintaining compatibility with the legacy `ADMIN_EMAIL`.
- Modified the admin login verification process to check against the list of root admin emails.
- Enhanced the admin role management in the frontend to reflect the new multiple admin structure.
