Expose optionUpdateBehavior prop on TimeseriesChart

[invisal]

This PR exposes the optionUpdateBehavior prop on TimeseriesChart, allowing consumers to control how ECharts applies option updates (e.g., notMerge, lazyUpdate, replaceMerge). The prop was already available on the low-level Chart component; this change simply passes it through from the higher-level TimeseriesChart.

optionUpdateBehavior?: SetOptionOpts;

// Destructured (line 146)
optionUpdateBehavior,

// Passed to Chart component (line 401)
optionUpdateBehavior={optionUpdateBehavior}

Review assessment:
