Adds a ready-to-use nginx config and docker-compose override that unifies Prowler UI (port 3000) and API (port 8080) behind a single port, solving CORS and auth failures behind reverse proxies. Includes nginx.conf, docker-compose override, and README with examples for Traefik, Caddy, and SAML SSO setup. Fixes prowler-cloud#8516

Fixes #8516
Problem
Prowler's default Docker setup exposes UI (port 3000) and API (port 8080) as separate services. This causes CORS issues and authentication failures when accessed through an external reverse proxy.
Multiple users have hit this — running behind nginx, Azure App Gateway, Pangolin, and other proxies.
Solution
Added a ready-to-use nginx reverse proxy config in
contrib/reverse-proxy/that unifies both services behind a single port:/api/*and/accounts/saml/*→ prowler-api:8080/*→ prowler-ui:3000Usage
Files added
contrib/reverse-proxy/nginx.conf— nginx routing configcontrib/reverse-proxy/docker-compose.reverse-proxy.yml— compose overridecontrib/reverse-proxy/README.md— setup guide with Traefik and Caddy examplesArchitecture
Pairs with the SAML ACS URL fix in #10533 for complete reverse proxy + SSO support.
