up 2.1.5

Add RealPingEvent sealed class and refactor real-ping flow to use event-driven communication. RealPingWorkerService now emits Progress/Result/Finish events instead of direct callbacks/MessageUtil calls. CoreTestService reorganized into handlers (handleMeasureStart/handleMeasureCancel/handleWorkerEvent) to process events, update notifications, persist delays via MmkvManager, and notify UI. MainViewModel adjusted to read the result content as a string when handling success messages. Overall change decouples worker logic from service responsibilities and simplifies progress/result handling.
