Add muni check during case lookup

[wdcrumpler-kcdd]

We need a way to identify when individuals are trying to expunge a municipal offense rather than a Kansas crime. Based on feedback from KLS, the easiest way to do this is likely to add a question during the case lookup phase that prompts them to look at the format of their case number.

To Do

• @wdcrumpler-kcdd to consult with @scott-stockwell to confirm how to phrase this question
• In meeting with KLS working group, review our suggested language to ensure that it is correct
