Related to #3253

Changes

• Fixes toggling off auto-add when dedupe is enabled
• Refactors auto-add and dedupe toggle to simplify save method
• Moves toast stack to below dialogs (related to [Feature]: Allow using app while upload is in progress #3253)
• Shows save status for auto-add and dedupe next to toggle

Manual testing

1. Log in as crawler
2. Go to a collection > Archived Items
3. Choose "Configure Items"
4. Find workflow with auto-add and dedupe enabled
5. Toggle "Auto-Add" off. Verify save status is displayed and disappears after 5 seconds
6. Reload browser window. Verify "Auto-Add" and dedupe for saved workflow remains toggled off

Follow-ups

A common component or render template should be created if we continue to follow this pattern. As a part of that work, the success status should be light-themed to match the success and info toast messages.

Tested locally and against dev, worked as expected in both places and makes for a nice experience.

Seeing some issues with rapid changes, as well as with the popover appearing over an interactive area, which is a little annoying. Could we move it above the item maybe, rather than to the left of it?

This should be fixed now.

I think the tooltip gets lost when it's above the item, testing on a collection with multiple workflows. Updated to place the tooltip on the right for large screens and decreased the duration to 4 seconds.

Nice! The one other odd thing I'm seeing is that it seems to animate to/from the wrong place when flipped to the left on smaller screens, I'm not sure if this is an upstream bug in shoelace though
