Fixes a visual regression where an operator's border, state text, port row counts, and worker count reset to default after navigating away from a workflow page and returning, even though the execution state is still cached in WorkflowStatusService. Root cause: WorkspaceComponent clears the workflow on destroy and calls reloadWorkflow() on re-init, recreating every operator from the workflow JSON with default JointJS attributes. The cached execution status was never reapplied, and the validation pass that runs on operator-add called changeOperatorColor(..., true) for valid operators, overwriting rect.body/stroke and forcing the border back to gray. Fix (two changes, both in workflow-editor.component.ts): Subscribe to getOperatorAddStream() inside handleOperatorStatisticsUpdate. When an operator is added (drag-drop, reloadWorkflow, undo/redo, collaborative add via Yjs - all routed through a single emission point), look up the cached OperatorStatistics. If present, call changeOperatorStatistics(...) to restore the state color, port labels, worker count, and state text. New operators with no cached entry early-return and get default coloring. Make handleOperatorValidation status-aware. Invalid operators still get a red border (priority preserved). For valid operators, the handler now checks the cached status - if one exists, it repaints via changeOperatorState(...) instead of overwriting with default gray. Valid operators with no cached status continue to get the default gray border.

Fixes #3614. ### How was this PR tested? Unit tests: Three tests added to workflow-editor.component.spec.ts under a new describe("operator border restoration after navigation") block: Valid operator + cached Completed -> changeOperatorState(..., Completed) is called. Valid operator + empty cache -> default changeOperatorColor(..., true) is called (existing behavior preserved). Invalid operator + cached Completed -> changeOperatorColor(..., false) is called, red wins (existing behavior preserved). All three pass under Vitest (ng test). Manual UI testing: Reproduced the issue's recording locally: Open a workflow (e.g., CSV File Scan → Radar Chart) and run it; both operators turn green with port row counts. Navigate to a different page, then back. Before fix: operators reset to default gray borders, row counts blank. After fix: green borders, row counts, worker counts, and "Completed" state label all persist. Edge cases manually verified: fresh workflow (default coloring), new operator dragged in after a completed run (default for new, cached for existing), re-running (resetStatus repaints Uninitialized, live updates flow normally), invalid operator with cached Completed (red border, validation priority). Note: workflow-editor.component.spec.ts was previously excluded from the default jsdom test target in angular.json. This PR removes that exclusion (so the new tests run in CI and contribute to Codecov coverage) and comments out six pre-existing mouse-event tests that fail under jsdom (they continue to pass in the ng run gui:test-browser target, marked with TODO(#3614) in place). A follow-up PR will revive those commented-out tests. ### Was this PR authored or co-authored using generative AI tooling?
