config: env-based service URIs via ConfigMap (prod: SOPS-encrypted)

- config.yaml: prod config with cluster-internal DNS (LLM, OpenSearch, Authentik, Temporal, API-GW)
- config.local.yaml: dev config with external URLs via ingress
- deployment.yaml: remove hardcoded URIs, read all from ConfigMap envFrom
- All downstream service URIs now configurable per environment
- Production config encrypted with SOPS (Age-based)
- Application code reads LLM_ENDPOINT, OPENSEARCH_HOST, AUTHENTIK_ISSUER, etc. from ENV
- Simplifies prod/dev switching: just swap ConfigMap, no code changes
