Fix email subject truncation to 100 chars

- Add truncation to existing working email subject logic (combined template names)
- Subject is truncated to 100 characters max with '...' suffix when needed
- Add test case for truncation with multiple templates
- Preserves existing behavior: subject = combined template names, body = concatenated email messages
