Refs #34527 - Add Host Collections card

[jeremylenz]

What are the changes introduced in this pull request?

• Adds a Host collections overview card to the host details page.
• add tests

Considerations taken when implementing this change?

I used flexbox rather than a table since it's such a simple layout. It worked out pretty well.
I had to add a few attributes to the rabl for host collections.
Dropdown menu items are disabled for now - they will be enabled in upcoming PRs.

What are the testing steps for this pull request?

• Add your host to at least 3 host collections
• Make sure at least one of the host collections has unlimited hosts
• Make sure at least one of the host collections does not have unlimited hosts
• Make sure some of your host collections have descriptions
• Also view a host that is not part of any collections - the card will be blank but the dropdown will still be accessible

Code looks good starting to test

Out of scope for this pr but I noticed we are changing a lot of rabl lately and we have like 1% test coverage in that area:

Do you think we should starting adding tests for when we change rabl?

Rabl is a view and we don't really test views too much, so I don't think it's needed in general
