fix(desktop): remove unused SCOPE_GENERATION_TEST_LOCK import in tests_captured_scope

The guard is invoked via the fully-qualified path
crate::managed_agents::scope::SCOPE_GENERATION_TEST_LOCK at :146,
matching the style in app_state_scope_tests.rs. The use-block import
added in b450d4693 is therefore unused and triggers clippy -D warnings.
