fix: gate dama doctrine test bundle config under when@test

Bundle was registered for test env only but its YAML config loaded
unconditionally, which broke `bin/console cache:clear` in dev/prod
when the bundle is enabled but the env doesn't load it. The file now
only contributes to the test container.
