gongme ingress: /api/* direkt an NestJS, SSE ohne Proxy-Buffering

OAuth2-Proxy und Next.js-Rewrites buffern SSE-Verbindungen, was dazu
fuehrt dass Verlaengerungen (SSE-Events) erst nach manuellem Reload
sichtbar sind.

Fix: /api/* wird jetzt direkt von Traefik an gongme-api:3001 gerouted,
ohne oauth2-proxy oder Next.js als Zwischenstufe. / (App + OAuth-Flow)
geht weiterhin durch oauth2-proxy. API-Sicherheit: Admin-Token + Session-Slug.
