chore: move PostgreSQL Grafana dashboard into dashboards/grafana/

 #### PostgreSQL storage backend
 
-New optional PostgreSQL output backend as a lighter-weight alternative to Elasticsearch/OpenSearch, configured via a `[postgresql]` section (host/port/user/password/database or a libpq `connection_string`). Tables are created automatically on first run, and the schema captures the RFC 9990 aggregate fields (`np`, `testing`, `discovery_method`, `generator`, `xml_namespace`, and per-result `human_result`). A Grafana dashboard (`grafana/Grafana-DMARC_Reports-PostgreSQL.json`) is included. Aggregate and SMTP-TLS reports are de-duplicated via `ON CONFLICT`; failure reports via an arrival-date / From / To / Subject check mirroring the Elasticsearch backend.

 The backend is opt-in: install it with `pip install parsedmarc[postgresql]` (it pulls in `psycopg`). It is not a mandatory dependency because the prebuilt `psycopg` binary wheels are not available for every platform.

 - [opensearch/opensearch_dashboards.ndjson](opensearch/opensearch_dashboards.ndjson) — the source-of-truth saved-objects export. It is imported into both **OpenSearch Dashboards** and **Kibana** (the file format is compatible with both).
 - [grafana/Grafana-DMARC_Reports.json](grafana/Grafana-DMARC_Reports.json) — the Grafana dashboard, with two Elasticsearch datasources (`dmarc-ag`, `dmarc-fo`).
+- [grafana/Grafana-DMARC_Reports-PostgreSQL.json](grafana/Grafana-DMARC_Reports-PostgreSQL.json) — the Grafana dashboard for the PostgreSQL backend.

 Edits to any of these files should be exported from a running instance after authoring the change in the UI, not hand-edited (with the occasional exception of small XML tweaks for Splunk).
