fix: resolve whitespace (wsl_v5) issues - part 1

- Fix whitespace issues in cmd files (example-mdns, example-upnp, soundtouch-cli, websocket-demo)
- Fix whitespace issues in client.go and websocket.go
- Fix whitespace issues in test files
- Restore accidentally removed deviceHost variable
- Add proper spacing around loops, conditionals, and function calls

Progress: Continuing to resolve remaining wsl_v5 linting issues
