Fix GitHub Actions workflow secret check

Fixed issue with checking secrets in if condition

Problem:
- GitHub Actions doesn't allow checking secrets.ENTITY directly in if:
- Error: "Unrecognized named-value: 'secrets'"

Solution:
- Move secret check to shell script within the step
- Use [ -z "$SECRET" ] for shell-based checking
- Script exits gracefully if secret not set

Allows workflow to run even without ELEVENLABS_API_KEY
