fix: allow paperless direct LLM access, bypass gateway JWT

- Add paperless namespace to llm-serving NetworkPolicy ingress
- Point paperless-ai CUSTOM_BASE_URL to reasoning-predictor directly
- Gateway JWT auth not yet available for service accounts
- paperless-ai-agent has llm:inference role in Authentik
