Simplify email subject handling and remove duplicate functions

- Remove send_success_email/send_error_email from email_sender.py
- Centralize subject logic in tasks.py using _get_subject()
- Use EMAIL_SUBJECT_SUCCESS and EMAIL_SUBJECT_ERROR with clear defaults
- Ensure subject is always set and logged before sending
