Updated tests/integration/test_vars_usage_in_yaml.py:
- Variables immediately followed by '(' are now treated as function calls,
not as set variables. This prevents false errors.
- Fixed detection of redirect_domain_mappings so it is no longer flagged
as unused.

- Renamed role `srv-tls-core` → `sys-svc-certs`
- Renamed role `srv-https-stack` → `sys-stk-front-pure`
- Renamed role `sys-stk-front` → `sys-stk-front-proxy`
- Updated all includes, READMEs, meta, and dependent roles accordingly
This improves clarity and consistency of naming conventions for certificate management and proxy orchestration.
