Health check (checks_stale_internet_radio.go): detects stub INTERNET_RADIO
sources (empty credentials) left on devices initialised before the stub was
removed from the default source list. Quick-fix removes by ID; skips any
INTERNET_RADIO source that has real credentials.
Datastore: DeleteSourceByID and DeleteSourceByType (uniqueness-guarded).
API: DELETE /setup/sources/{account}/{device}/{sourceID}
CLI — two new commands:
soundtouch-cli cloud source remove --service-url ... --account ... --device ... [--id 10002 | --type INTERNET_RADIO]
Talks to AfterTouch (service side). --type resolves to canonical ID
locally; fails for unknown types.
soundtouch-cli source notify-updated --host <speaker-ip>
Talks to the speaker directly. Fetches device ID from /info, then
POSTs sourcesUpdated to :8090/notification so the speaker re-fetches
its source list immediately.
CloudCommonFlags (--service-url / AFTERTOUCH_URL) mirrors CommonFlags
(--host) for AfterTouch-facing command groups.
