Subject: [PATCH] If NEXT_PUBLIC_PROJECT_URL is not set, default to host URL

If NEXT_PUBLIC_PROJECT_URL is not set, default to the URL where the page is being hosted. This will be useful if people use the Railway button cause there is know way to default to the given *.up.railway.app url beforehand. This worked in my crude test.
