feat(lifecycle_client): add MwLifeCycleManagerMock for OSS consumers

[Chahult]

Closes #265

• Add MwLifeCycleManagerMock that intercepts LifeCycleManager::report_running() and LifeCycleManager::report_shutdown() via global GMock callbacks, allowing unit tests to set expectations on both methods without real IPC calls to the Launch Manager.
• Remove the empty report_running() stub from lifecyclemanagermock.cpp; it is now owned by mwlifecyclemanagermock.cpp with a null-safe callback dispatch.
• Move report_shutdown() out of the inline header body and into lifecyclemanager.cpp (empty no-op) to allow the mock translation unit to provide a separate definition.
• Add mw_lifecycle_manager_mock Bazel target and mw_lifecycle_manager_mock_cc public alias in //score/launch_manager.
• lifecycle_mock now depends on mw_lifecycle_manager_mock so existing consumers of lifecycle_mock continue to link without changes.
• Add MwLifecycleMockTest fixture and two tests to lifecycle_mocks_UT.cpp.
