feat: update email configuration and enhance email sending functionality

- Changed EMAIL_SENDER in values.yaml to a new email address.
- Updated EMAIL_SENDER_PASSWORD key reference in values.yaml for improved security.
- Added PostgreSQL configuration parameters to values.yaml for database connectivity.
- Refactored Email class to include a new send_email method for better error handling during email transmission.
- Implemented reconnection logic for SMTP server disconnections to ensure reliable email delivery.
