Create workflow version show page (#7466)

In this PR:

- Refactored components to clarify their behavior. For example, I
renamed the `Workflow` component to `WorkflowVisualizer`. This moved
forward the issue #7010.
- Create two variants of several workflow-related components: one
version for editing and another for viewing. For instance, there is
`WorkflowDiagramCanvasEditable.tsx` and
`WorkflowDiagramCanvasReadonly.tsx`
- Implement the show page for workflow versions. On this page, we
display a readonly workflow visualizer. Users can click on nodes and it
will expand the right drawer.
- I added buttons in the header of the RecordShowPage for workflow
versions: users can activate, deactivate or use the currently viewed
version as the next draft.

**There are many cache desynchronisation and I'll fix them really
soon.**
