This is a squash of a lot of scattered commits that became very difficult to clean up and make individually. Sorry.
Besides the new UI, there are a number of notable changes:
- Publishing logic is disabled in OSS by default. To enable it, provided a `disabledFeatures` prop _without_ "publishWorkflow".
- Enqueuing a workflow is no longer handled in a redux listener. It was hard to track the state of the enqueue logic in the listener. It is now in a hook. I did not migrate the canvas and upscaling tabs - their enqueue logic is still in the listener.
- When queueing a validation run, the new `useEnqueueWorkflows()` hook will update the payload with the required data for the run.
- Some logic is added to the socket event listeners to handle workflow publish runs completing.
- The workflow library side nav has a new "published" view. It is hidden when the "publishWorkflow" feature is disabled.
- I've added `Safe` and `OrThrow` versions of some workflows hooks. These hooks typically retrieve some data from redux. For example, a node. The `Safe` hooks return the node or null if it cannot be found, while the `OrThrow` hooks return the node or raise if it cannot be found. The `OrThrow` hooks should be used within one of the gate components. These components use the `Safe` hooks and render a fallback if e.g. the node isn't found. This change is required for some of the publish flow UI.
- Add support for locking the workflow editor. When locked, you can pan and zoom but that's it. Currently, it is only locked during publish flow and if a published workflow is opened.
