fix(tests): restore ping() method and cleanup wsPingSetInterval

Fixes Windows CI hang caused by:
- Missing wsPingSetInterval cleanup in cleanupChargingStation()
- Removed ping()/pong() methods that ChargingStation.ts still calls

The WebSocket ping interval was never cleared during test cleanup,
keeping the Node.js event loop alive indefinitely on Windows.
