fix: resolve more whitespace (wsl_v5) issues - part 2

- Fix whitespace issues in test files (bass_test.go, client_test.go, source_selection_test.go)
- Fix whitespace issues in discovery/mdns.go
- Fix whitespace issues in config/config_test.go
- Fix whitespace issues in soundtouch-cli main.go ranges and loops
- Fix whitespace issues in models/websocket_test.go

Progress: Reduced wsl_v5 issues from 50 to 45 (10% improvement)
Total remaining: 79 issues (down from 84)
