Fixes CodeQL go/log-injection alerts in the final batch of packages.
New logutil.go helpers: pkg/client, pkg/testutils/amazon,
pkg/testutils/spotify, cmd/soundtouch-service, cmd/soundtouch-web,
cmd/dummy-speaker, cmd/mdns-scanner.
pkg/discovery/logger.go: added sanitizeLog and a nil-safe
remoteAddrString helper to the existing file (alongside logVerbose).
Call sites wrapped across 11 files — device IDs, source types,
hostnames, IPs, interface names, URLs, service names, HTTP method/form
values, WebSocket URLs and payloads, TLS SNI names, remote addresses.
No behaviour change. golangci-lint and make check pass.
