make customer deployment test optional when secret missing

- Change fatal error to warning when WG_EASY_CUSTOMER_EMAIL secret is missing
- Add conditional execution for customer/cluster creation and helm install test
- Allows workflow to complete successfully for basic validation without customer secrets
- Enables testing of build, lint, and release steps in environments without full secrets
