fix: improve graceful shutdown for systemd services

- Add lws_cancel_service() to immediately wake up WebSocket event loop
  during shutdown instead of waiting for 50ms timeout
- Fix race condition in HttpServer where both Stop() and Wait() tried
  to join httpThread_, causing undefined behavior from signal handlers
- Implement self-pipe pattern in database for async-signal-safe shutdown
  notification (gRPC Shutdown() is not safe to call from signal handlers)
- Split GrpcServer::Stop() into RequestShutdown(), Wait(), and Cleanup()
  to properly separate signal-safe and non-signal-safe operations
- Add TimeoutStopSec=10 to systemd service files as fallback

Before: Services took 10+ seconds to stop (hitting SIGKILL timeout)
After: Services stop cleanly in ~20-40ms with proper cleanup
