Refactor role naming for TLS and proxy stack

- 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.
