Content Type Workspace: Create condition that checks content type uniques.

[engijlr]

Summary

Adds a new workspace condition Umb.Condition.WorkspaceContentTypeUnique that checks content types by their GUID/unique identifier instead of alias.

How to test

1. Create a new document type (e.g., "Test Page")
2. Copy the GUID from the URL (it will look like: d2d7572e-1ba1-458d-a765-95b60040c3ac)
3. Run the example: npm run example and choose option 6 - entity-content-type-condition
4. Open examples/entity-content-type-condition/index.ts and paste the GUID you copied into the match/oneOf property.
5. Navigate to a document of the type you created you should see the "Conditional (Unique)" workspace tab appear.

Hi @engijlr

This looks really good! I have a bit of trouble running the example because of a const import that points to something wrong, but the code looks like it does what it should.

I have added a few comments around code style and naming where I think we can make some improvements for alignment and readability.

Let me know when you have had a look at the example, then I will try it again.
