adding import export session

[StevenLAdler]

should it add users/items in the import when they dont already exist in DB?
should it auto clear on an import?
is 'unique' the correct field to match items?

tested and passing

1. No, it should fail.
2. I think if we consider them as save/load, then yes it should clear beforehand
3. '_id' is the field you should match items on.

Ask chatgpt to write you some tests, usually that gets you 80-90% of the way there. That's what I've been doing and it still catches a bunch of issues.

The git workflow doesn't run pytests, I couldn't get that to work last I tried. You'll have to run pytest locally before pushing. There's a couple other small things in there to address as well.

Also, I realize two of my comments weren't added to the review, but once I added them, I couldn't figure out how to do it without deleting them, so they're not in it technically?

Looks good, just two small things
