Refactor store for better readability

**Feature request**
It would be great to have sorting for controllers.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_sorting` with default `false`.

Start by locating the controller store and the configuration parsing or defaults that govern it. Check how controllers are currently collected and whether existing tests cover that path. Done means an `enable_sorting` option defaults to false and, when enabled, controllers are sorted consistently; add or update tests for both settings.
