Subject: [PATCH] Fix TeslaMate/UnPoller dashboard UID sed clobbering
 datasource refs

The previous sed replaced ALL "uid" fields in dashboard JSON files,
including datasource references inside panels, causing dashboards to
go dark. Scope the replacement to only the first occurrence (the
top-level dashboard UID) using GNU sed 0,/pattern/ addressing.
