Remove all tracking JS from theme assets
- This change replaces the uom.js and uom.css files. Primarily this removes the unused JS tracking assets from uom.js. These files were generated using the following fork: https://gitlab.unimelb.edu.au/resplat-data/unimelb-design-system. This makes the page load faster, as well as avoiding serving tracking scripts to users.
- Removed the JS tracking script from base.html.
