Onsite dev

[hannahker]

Development work from the onsite Hackathon:

• Integrating changes to export pixel mask
• Add submit job button to UI
• Add placeholder callback to run model

I've overlapped with some of @tamidodo's work in #57. The code here is a quick initial implementation so could be replaced by #57 once that's finalized.

Please excuse the last 6 commits as I was getting a weird layout error when deploying...

Feels like there is probably a dumb reason behind this... but for the life of me I can't figure out why we have this error in the deploy logs on the staging app:
