Migrate a specific erkenningen CommandHandling/ folder from the old Kbo/Vzer subfolder pattern to the new ErkenningScenarioBuilder pattern. Use when asked to migrate a specific "When_*" erkenningen commandhandling test folder.

Refactor command handler tests under a CommandHandling/ folder by extracting repeated boilerplate (fixture, scenario, mock, handler) into a composition-based context class. Use this when asked to refactor or rewrite existing command handler tests.
