Fixed Third Party Licenses 404 Issue on GitHub Pages

[sammy0318]

Closes #311
The Third Party Licenses page (/help/thirdPartyLicenses) was showing a 404 error when accessed directly through the GitHub Pages URL. This issue occurred because GitHub Pages doesn't natively support client-side routing used by React Router.

Solution:-
Modified the routing configuration to properly handle client-side routing on GitHub Pages:

Added a custom 404.html page with a script to redirect to the main application
Updated the index.html with a script to handle the redirect parameters
Changed from BrowserRouter to HashRouter for better GitHub Pages compatibility
Added homepage field to package.json

Changes

Created new 404.html in public folder
Added redirect script to index.html
Modified Routes.jsx to use HashRouter
Updated package.json with correct homepage URL

Testing

All routes now work with direct access
Navigation within the application works as expected
Third Party Licenses page loads correctly when accessed directly
