Flow Viewer: Snapshots

[joepavitt]

Implement the https://github.com/FlowFuse/flow-renderer in the FF product, by adding the option to visualise any Snapshots.

Design for the modal viewer for the flows themselves available here: #3768 although need to add the specifics of accessing/opening this from the "Snapshots" view.

• Generate a top level API for snapshots #3828
  • Visualise a snapshots flows #3835 (dependant on the above)
  • Add change log entry for Viewing snapshots flows
  • Update docs-user-snapshot to include a description of the view snapshot feature

Switching to #3803 as first iteration as the APIs for Snapshots are a little more complicated than we need. The only way of getting the flow.json equiavelent would be using /export API end point, which is excessive for what we need here. As such, a new /flow endpoint (or something similar) should be built to better enable this viewer for snapshots

Interesting comment, I was going to ask what the design is for showing env vars, NR version, etc etc. :) Team library might indeed be a quicker win

Design for the modal viewer for the flows themselves available here: #3768 although need to add the specifics of accessing/opening this from the "Snapshots" view.

In a first iteration, there are 2 relatively basic approaches:

1. The snapshot tables kebab menu gets a new option "View Snapshot"
   1. NOTE: not all snapshot tables have the kebab menu so would need to be added (Applications, Devices)
   2. Related: Add appropriate Snapshot actions to all snapshot table views #3815
2. The tables get a new slim column with only a button 👁️

NB: Since #3815 will require the snapshot tables to have a kebab menu, I would favour option 1.

What is not explicitly mentioned is who can view it but since the "Download Snapshot" #3627 feature is scoped to "Member", that would be a starting point.

re-open for 2 follow on issues in the task list

Keeping this in the "Review" column to make sure we don't lose track of it
