Now that we have a logo, we should use customized favicons in PAWS.
We have several different pages with different favicons in jupyterhub, it would be ideal to use custom favicons based on the logo for each different "state" indicated by favicons.
- Hub favicon (has none in vanila jupyterhub). This is the simplest case, we can just use the favicons from T179677
- Initial notebook server favicon (maybe we can repeat the one from the hub)
- Notebook open favicon
- File open favicon
- Terminal favicon
- Animated notebook busy favicon 1 2 3
The first two are the main focus at the moment, not sure we want to change the others.
