index.html with relative paths to css and js files

[krandalf75]

Make poly more reverse proxy friendly: Use relative paths to load javascript and css so they are loaded from /poli/static instead /static. So we don't need to publish /static folder.

Hey man. Thanks for the PR. I tested it and it works well. The only problem is if I refresh the page for example, http://localhost:6688/poli/workspace/report. All resource files are redirected to http://localhost:6688/poli/workspace/static/css/2.07f54ecf.chunk.css from http://localhost:6688/static/css/2.07f54ecf.chunk.css and return 404.
