chore(news-bot): switch to siriusdevops-pgdb as main apps cluster

- news-app-db.yaml: point Database CR to siriusdevops-pgdb
- All ConfigMaps: DB_HOST=siriusdevops-pgdb-rw, LLM_BASE_URL for vLLM
- hermes-pgdb now dedicated to pgvector/RAG for agents only
- Aligns with CNPG extension pattern and active kanban (devops startupProbes, backend exec-service)

PR to master per repo rules.
