    test(frontend): add unit tests for WorkflowRuntimeStatisticsComponent 
(#6580)
    
    ### What changes were proposed in this PR?
    
    Adds a Vitest unit spec for `WorkflowRuntimeStatisticsComponent`, which
    previously had no test coverage. The 9 tests cover:
    - `ngOnInit` grouping stats by operator id and calling `Plotly.newPlot`
    once (metric 0), asserting the `(chartId, dataset, layout)` args.
    - the undefined-statistics guard (warns, no plot).
    - `groupStatisticsByOperatorId`: nanosecond-to-second conversion,
    timestamps made relative to the first stat, grouping repeated operator
    ids, and skipping stats missing an operator id.
    - `createDataset`: sink-operator removal and
    `<operatorName>-<last6ofId>` series naming with `x = timestamp / 1000`.
    - `onTabChanged` re-plotting with metric-specific y-values (input-count
    vs worker-count).
    - `createChart` warn-and-skip when the dataset is empty (sink-only and
    empty-stats).
    
    `Plotly` (`plotly.js-basic-dist-min`) is mocked; `NZ_MODAL_DATA`
    supplies the fixtures.
    
    ### Any related issues, documentation, discussions?
    
    Closes #6577.
    
    ### How was this PR tested?
    
    `npx ng test --watch=false
    --include='**/workflow-runtime-statistics.component.spec.ts'` -> 9/9
    passing. `yarn format:ci` passes.
