Display data saved to server

[jgfoster]

We would like to have a web site that displays info on connected devices. We do have devices uploading current data every minute as well as changes as they happen. This data is stored in root@oap:/var/opt/oap/logs. We want a web app that can server these files and interpret/display the data.

Tasks:

• Ensure that device is sending data to server (largely done as part of Send alert to e-mail or phone #360)
• Ensure that server is accepting data and saving it (it was at one time but last upload was in October 2023?)
  • Is this a custom app or just the normal feature of the web server?
• Ensure that server can provide files that have been uploaded
  • Should just be part of the web server with a path to /var/opt/oap/logs
• Web app to display files and interpret the data
  • New Flutter app

Step 0 was partially implemented with https://gitlab.cs.wallawalla.edu/cs_lab/ansible-configuration/-/merge_requests/143 (note that the link is internal to the CS Lab at WWU).
