Inspect routes to detect classes that may require reflection

Assuming we have a route that contains something like:

.bean(OrderService.class, "doSomething")

Then the `OrderService` should be listed among the classes that require reflection.

Start by tracing how routes are inspected and how classes requiring reflection are collected. Use the example route containing `.bean(OrderService.class, "doSomething")` as the acceptance case; done means `OrderService` is listed among the classes requiring reflection.
