Fix long-running progress and compact the workbench

[JustAGhosT]

Summary

• default the authenticated workbench to a balanced stage + history layout, with compact collapsible path and history panels
• replace the synthetic video percentage plateau with honest indeterminate elapsed-time feedback
• close the Azure Blob service client used by retained conversion artifacts

Production evidence

The reported 88% state was synthetic frontend progress. The authenticated production conversion completed successfully after about 2m53s, refreshed history, and served its retained download. Azure logs also exposed the Blob client lifecycle leak fixed here.

Validation

• frontend: 20 tests passed
• frontend lint: clean
• frontend production build: passed
• backend artifact storage: 9 tests passed
• git diff check: clean

Follow-up

Baton a7b2cdab tracks durable asynchronous jobs followed by opt-in completion notifications.

Summary by CodeRabbit

  • Improved transformation navigation, history actions, and upcoming route displays.
  • Enhanced accessibility and reduced-motion support for progress indicators and controls.

• Bug Fixes

  • Improved cleanup of storage resources after artifact operations.
  • Prevented misleading percentage progress from appearing during indeterminate processing.

📝 Walkthrough

Walkthrough

The change closes all Azure storage clients, adds collapsible workbench panels, updates responsive layouts, and replaces simulated video percentages with indeterminate progress and elapsed-time feedback. Tests cover resource cleanup, panel controls, route access, and video progress behavior.

Changes

Artifact storage lifecycle

Layer / File(s)	Summary
Azure resource cleanup backend/services/artifact_storage_service.py, backend/tests/test_artifact_records.py	Azure operations now close credential, service, and container clients. Tests mock all three resources and verify closure after upload.

Transformation workbench

Layer / File(s)	Summary
Progress feedback frontend/src/components/ProgressBar.jsx, frontend/src/TransformationApp.jsx, frontend/src/App.css, frontend/src/TransformationApp.test.jsx	ProgressBar supports indeterminate progress and detail text. Video transformations show elapsed time and long-running-operation messaging without a fabricated percentage.
Workspace panels and responsive layout frontend/src/TransformationApp.jsx, frontend/src/components/TransformationHistory.jsx, frontend/src/App.css, frontend/src/TransformationApp.test.jsx	Transformation paths and history can collapse and reopen. Route metadata uses live and upcoming counts. The workbench uses responsive grids and stacked mobile layouts.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk:🔵 Low · up to 93082

The workbench currently shows history immediately instead of keeping it collapsed by default, creating a bounded UI correctness issue for authenticated users. The PR is otherwise mergeable with owner awareness and a small follow-up to correct the initial history state.

Poem

A rabbit sees progress glide,
No false percent hops beside.
Panels fold with a gentle cheer,
Azure clients close clean and clear,
While routes bloom in grids far and wide.
