Spike Import exported clinic

[steventux]

Description

Here's a demo of how we could export a clinic's worklist from Rubie and import it using a minimal UI on the Gateway.
This decouples the connection between the two applications allowing for offline mobile van processing.

The counterpart export worklist and import resulting offline DICOM zip archive is here: https://github.com/NHSDigital/dtos-manage-breast-screening/pull/1921

The spiked worklfow steps are:

1. While online, an admin/clinical user exports the clinic worklist from Rubie.
2. The worklist file is saved somewhere that can be used in a mobile screening van.
3. The worklist file is imported using the Gateway UI, this populates the Modality Worklist Server on the Gateway in the same way that sending individual worklist items over a Relay would.
4. Screening takes place in the mobile unit.
5. Assuming the mobile unit does NOT have internet connectivity, the resulting DICOM files remain on the Gateway's PACS server, they are not sent back to Rubie.
6. The user can then export these DICOM files as a zip archive and save them.
7. The zip archive can then be uploaded back into Rubie when an internet connection is available.

The spike enables an airgapped export -> import -> export -> import of Worklist and DICOM files emulating some of the offline NBSS behavour.

It comes with some significant caveats:

• We do not handle the transport of data which would normally be persisted in Rubie as the appointment progresses eg. recording additional medical information.
• It is necessary to run a web server on the Gateway for the UI enabling import and export of data.
• The addition of the NHSUK frontend toolkit and other webserver dependencies more than double the size of the Gateway release package.
• We could possibly achieve the same import/export functionality without UI at the cost of a steeper learning curve for admins or clinicians.
• Moving data in a disconnected state like this means that the Gateway would need to be deployed within the mobile unit itself. This presents some technical challenges with how we would install/update Mobile Gateways.
