[job-hunter] Add infra stack + Grafana dashboard + n8n digest workflow
New service stack at stacks/job-hunter/ mirroring the payslip-ingest pattern: per-service CNPG database + role (via dbaas null_resource), Vault static role pg-job-hunter (7d rotation), ExternalSecrets for app secrets and DB creds, Deployment with alembic-migrate init container, ClusterIP Service, Grafana datasource ConfigMap. Grafana dashboard job-hunter.json in Finance folder: new roles per day, source breakdown, top companies, GBP salary distribution, recent roles table (sorted by parse confidence then salary). n8n weekly-digest workflow calls POST /digest/generate with bearer auth every Monday 07:00 London; digest_runs table provides idempotency.
