Document ia.enso nginx proxy (operator guide, cross-links)
**Motivations:**
- Single operational reference for deploy script vs manual steps and troubleshooting.
**Root causes:**
- README mixed http-maps manual path with script using conf.d without full operator context.
**Correctifs:**
- Align documentation with deploy script paths and prerequisites.
**Evolutions:**
- Expanded README-ia-enso.md (tables, SSRF context, env vars, rotation, troubleshooting).
- Feature doc table and deployment pointers; links from docs/README, infrastructure, services.
**Pages affectées:**
- deploy/nginx/README-ia-enso.md
- docs/features/ia-enso-nginx-proxy-ollama-anythingllm.md
- docs/README.md
- docs/infrastructure.md
- docs/services.md
