Nginx conf returns 404 on non-root paths

[applejag]

The built nginx image is misconfigured so it returns status code 404, even though it still returns the index.html body, on any non-root endpoints (ex: /project/1).

Seems to be that it's looking for the file /usr/share/nginx/html/project/1, so we need to add some routing in the nginx config to always return the index.html and let Angular deal with the 404 routing
