fix: Enhance multiframe instance handling and improve instance validation

- Updated `getDisplaySetInfo` to ensure local file frame imageIds resolve correctly, falling back to the source multiframe instance when necessary.
- Improved instance filtering in `isDisplaySetReconstructable` to handle undefined instances more robustly.
- Modified `App` prop types to make `routerBasename` optional and added new props for loading indicators and data sources.
- Refactored `CinePlayer` component to replace Button with a div for better accessibility and interaction.
