[Feature Request] Debug existing rules

### Summary:

When prompted about a new connection it'd be nice to be able to understand why a certain rule didn't apply to the connection.

### Use case

- I start a new application and shortly add a new rule for it.
- Later, I get a new prompt for a new connection from the same App
- However, I think that it should be captured by the existing rule.

#### Today

- I just write a new rule, and then try to do a side-by-side diff to understand how my first rule missed this case, and then fix the first and only rule.

#### With debugging UI

- I select which rule should've covered this case.
- The UI shows my what rule matchers passed and which ones failed so I can better understand why the rule didn't work.
- I notice an error and fix the existing rule by relaxing constraints around all the missed rule matchers.
