[reconfigurator-cli] Populate simulated caboose and test RoT update

[karencfv]

This turned out to be way easier than I anticipated. @jgallagher I know this clashes with your host OS planner PR, happy to hold off merging this until you merge your PR if you prefer 😄

Related: #8798

Tufaceous uses the board name as the sign for the artifact's cabooses

We can do the same here

I think it's fine to land this before the host OS planner stuff; that's going to be a little while longer before it's ready. If you change the inputs to use latest instead of raw UUIDs, fixing up the merge conflicts shouldn't be too bad.

I realized this way too late when I was working in this file, but: you can change all of the blueprint-plan lines to

Suggested change

	blueprint-plan dbcbd3d6-41ff-48ae-ac0b-1becc9b2fd21 f45ba181-4b56-42cc-a762-874d90184a43
	blueprint-plan latest latest

(for "base of the latest blueprint" and "use the latest collection") to avoid having to manually shuffle all these UUIDs around when we make changes.

[jgallagher]

Similarly, all of these can be just

Suggested change

	blueprint-diff dbcbd3d6-41ff-48ae-ac0b-1becc9b2fd21 8da82a8e-bf97-4fbd-8ddd-9f6462732cf1
	blueprint-diff latest

for "diff the latest blueprint against its parent".

I've merged #8664. So, I'll update this PR to include RoT bootloader tests as well. I can't merge this PR as is because once the cabooses have a SIGN the planner automatically tries to update the RoT bootloader before the bootloader.

[karencfv]

Ugh, I don't know what is going on here. I merged main into my branch and it still says there are branch conflicts 😒

EDIT: #8631 was merged 😄

[karencfv]

I've updated the PR to include testing RoT bootloader as well. Would appreciate another look!

[karencfv]

Will merge as it had merge conflicts a couple of times now and tomorrow is Saturday for me. It's only tests so we can adjust these if necessary.
