feat: Allow Document to be fetched without Slug (#3453)

* Allow Document to be fetched without Slug

Fixes #3423

This PR refactors the `Document.findByPk` method to not require the
`slug` portion of the urlID.

Before this function accepted two different 'formats' for the ID.

 - The `uuid` ID of the Document
 - The full `urlID` which looked something like
   `some-document-1234567890`

However the `some-document` slug portion of this identifier wasn't
actually used when looking for a document.

We now allow searching by JUST the postfix of the `urlID`, in the above
example that is `1234567890`.
We do this via a new Regex pattern to match on that just looks for the
right looking id alone, without the prefix.

This codepath looks the same as when we find it by the full `urlID`
besides the different regex that we match on.

The issue #3423 mentions that this should apply to all the API
endpoints. I believe that this `findByPk` method is all that should be
needed for that change. But if this is incorrect, OR you would like more
test coverage on the API endpoints as a more 'end to end test' please
let me know!

* Change original regex to make the slug optional

This has the, I believe to be good, side-effect of making the same logic
apply to `Collection` as well. Since `Collection` was always doing the
same stripping of the slug before the lookup I believe it should be just
as safe to do there.

We don't have to touch the code in Collections but we add a test of this
behavior there as well.

* No reason to rename this now that we aren't doing two matches
