Add a unfiltered route

In this route, classes will be displayed as they are in the config editor, not filtered by name and such. This ensures that all the classes properties are present and makes it easier to search for people who are familiar with config entries

Start by locating the existing route that filters classes by name and tracing how it loads class properties for the config editor. Add the unfiltered route alongside that entry point, then verify that it returns all classes with their complete properties and does not apply name filtering.
