deleteTrainingPlan
destructive
`DELETE /trainingplan-service/trainingplan/trainingplan/{planId}` (the `trainingplan` segment really is doubled) — the request Garmin Connect's "Quit Plan" sends, observed in the web client on 2026-10-06. Resolves `null` (204); the plan's scheduled workouts leave the calendar, completed activities stay. A second call is a 404 `"Training plan not found with ID: …"`. IRREVERSIBLE
