Subject: [PATCH] fix(metrics): normalize docker resource type in metrics
 history API (#1229)

Frontend sends resourceType="docker" but the SQLite store uses
"dockerContainer". The /api/metrics-store/history handler now
normalizes the alias so queries return the correct historical data
instead of falling back to a single live data point.
