Bug: Missing legend updates for two LINE chart widgets

The PR aims to add legends to query module charts by populating the name field in widget queries, but two LINE chart widgets (metrics-throughput-line and metrics-duration-line) were missed. Their queries[0].name fields remain empty strings (lines 189 and 220), and their title fields use hardcoded strings instead of the new constants (lines 182 and 212). This means these charts won't display legends in tooltips like the other updated widgets.
