fix(ops/nginx): sync configs aus /etc/nginx/sites-available/ vom rebreak-server

Mein vorheriger Push hatte ältere ops/nginx/-Versionen aus dem rebreak-monorepo.
Server hatte ACME-Challenge, security-Headers (HSTS, X-Frame-Options, X-XSS),
separate /webhook Location, X-Robots-Tag — alles war im Repo nicht drin.

Geänderte/neue files:
- staging.rebreak.org.conf — full version mit ACME + security
- db-staging.rebreak.org.conf — minimal diff
- default.conf — NEU
- rebreak-staging-new.conf — NEU

Live nginx selbst war nicht betroffen (nginx -t ok), Repo-Sources jetzt
auf Live-Stand synchronisiert.
