test: use real BLEInterface instances for coverage tracking
Replace Mock-based fixtures with real BLEInterface instances in stale identity check tests. This ensures coverage.py properly tracks execution of production code paths. The Mock approach with method binding executed the production code but coverage tracking was inconsistent. Using real instances guarantees proper coverage attribution.
