When Grafana's [dataproxy] send_user_header is enabled, Grafana adds an X-Grafana-User header with the logged-in username to all data source proxy requests. This commit logs this header in the query frontend's query stats, slow query, and query request log messages, making it easier to attribute queries to specific Grafana users. The header is already logged alongside X-Dashboard-Uid and X-Panel-Id in the formatGrafanaStatsFields helper, so it appears in all three logging paths automatically.
