feat(configgen): Phase 2 Config-Generator + nginx → HAProxy-only Pivot

Browse Source 
Architektur-Pivot: nginx fällt komplett weg. HAProxy 2.8+ übernimmt
TLS-Termination, L7-Routing per Host-Header und LB. ACME-Webroot
und Management-UI werden von edgeguard-api ausgeliefert (Phase 3
implementiert die zugehörigen Handler); HAProxy proxied
/.well-known/acme-challenge/* und Management-FQDN-Traffic an
127.0.0.1:9443. Eine Distro-Abhängigkeit weniger, ein Renderer
weniger, sauberere Trennung.

Renderer (alle mit Embed-Templates + Tests):
* internal/configgen/  — atomic write + systemctl reload helpers
* internal/haproxy/    — :80 + :443, ACME-ACL, Host-Header-Routing,
                         Stats-Frontend, api_backend Fallback
* internal/firewall/   — default-deny input, stateful baseline,
                         SSH-Rate-Limit, :80/:443 accept,
                         Cluster-Peer-Set für mTLS :8443,
                         Custom-Rules aus PG
* internal/{squid,wireguard,unbound}/ — Stubs (ErrNotImplemented)

Orchestrator + CLI:
* internal/services/configorch/  — fester Reihenfolge-Run, Stubs
                                   sind soft-skip statt fatal
* cmd/edgeguard-ctl render-config [--no-reload] [--only=svc1,svc2]

Packaging:
* postinst: /etc/edgeguard/nginx raus, /var/lib/edgeguard/acme rein,
  self-signed _default.pem via openssl req (damit HAProxy startet
  bevor certbot etwas issuet hat)
* control: Depends nginx raus, openssl rein
* edgeguard-ui: dependency auf nginx weg, "Served by edgeguard-api
  gin StaticFS"

Live-Smoke: render-config gegen lokale PG schreibt /etc/edgeguard/
haproxy/haproxy.cfg + nftables.d/ruleset.nft korrekt; CRUD-Test aus
Phase 2 läuft weiter unverändert.
