[3.9-WW] Improve Web Worker Integration and Documentation: Enhance web worker support, documentation, and user experience.

[sedghi]

What feature or change would you like to see made?

• Provide comprehensive documentation on using web workers in OHIF, including best practices and guidelines
• Implement a service or API for interacting with web workers, abstracting away low-level details
• Introduce UI elements or indicators to inform users when a web worker task is running or in progress
• Explore utilizing existing UI component libraries (e.g., @Shadcn/ui,Sonnet) for visually representing web worker tasks and their status
• Address potential issues or scenarios involving multiple concurrent web worker tasks or background operations

• related https://www.cornerstonejs.org/docs/concepts/cornerstone-core/webWorker

Why should we prioritize this feature?

Web workers offer significant performance benefits by offloading computationally intensive tasks to separate threads, improving the overall responsiveness and user experience
