Implement Geant4 dataset cache management and status monitoring

[grzanka]

This pull request introduces a comprehensive browser cache status detection and UI for Geant4 datasets, allowing users to see which datasets are cached locally, how much storage is used, and whether downloads are required. The changes add a new dataset cache service, a React hook for cache status, and UI components to visualize cache status in both the main simulation panel and the full info modal dialog.

Core functionality for cache detection and UI:

Backend/cache service additions:

• Added Geant4DatasetCacheService.ts to detect, query, and clear Geant4 dataset cache from IndexedDB, including dataset definitions, cache status calculation, and browser storage usage estimation.

Frontend/cache status hook:

• Added useDatasetCacheStatus.ts React hook to provide cache status, storage usage, and refresh/clear actions for use in UI components.

UI integration in simulation panel:

• Integrated a new CacheStatusIndicator component into Geant4DatasetDownload.tsx, displaying cache status, storage usage, and per-dataset indicators, with automatic refresh after downloads complete. [1] [2] [3] [4]

UI integration in modal dialog:

• Added a cache status section to DatasetsFullInfoModal.tsx, showing cache summary and per-dataset status, and updated explanatory text to reflect the new cache status feature. [1] [2] [3]

I noticed two things

1. when download is done and I move to other tab (i.e. Editor) and back, the Dataset Download is open for split second and collapsed again, this doesn't look good

2. I can clear the datasets and the Start Simulation is still valid - now that I see it, I'd consider making it grayed out in this situation
