Branching history view/restore parameters

[space-nuko]

Needs improvements:

• Performance is bad with lots of nodes
  • Linear view is better served as a virtual list like the normal history pane
  • History tree should be pruned when it gets too large
• Parameters should be excludable from patch history, but includable in parameter restore, instead of both or none
  • Exclude both: image uploads, gallery view, display-only widgets (width/height preview for scale by modes)
  • Exclude from patch only: seed (randomized every gen, but doesn't make sense to branch off a new history for each seed change)
• Parameter restore only shows the name of the individual parameter - just TEnc for a single LoRA weight - so it's difficult to associate which grouped parameter changed
  • At least include the names of containers the widget is contained in for better identification
• Hovering a history node should show the diffs of the parameters in the UI, instead of just highlighting the changed UI elements
  • Also, can't see the highlights if the widget is off-screen
• Restore parameters patches don't include combo widget parameters for some reason
• Default workflow needs to be updated to support patch parameter exclusion
