fix(security): remove hardcoded AWX credential from script

The AWX admin password was hardcoded in scripts/awx_create_job_templates.py.
Read credentials from environment variables instead (AWX_USER,
AWX_PASSWORD, AWX_URL) and fail loudly when AWX_PASSWORD is unset.

No credentials are stored in this repository.
