I think this really boils down to what you call application logic.

Manipulating the database (i.e. what DBIx::Class does) isn't the kind
of logic I was talking about. I meant actual business logic. This
means things like validation (not that the other layers shouldn't
validate data), access control, bridging your model and your view,
triggering model actions, etc.

IMO, the controller should be responsible for the higher level logic
involved in an application while the logic contained in the model is a
lower level (i.e. implementation details), usually data oriented,
logic.
