Add real-JSON CGM reading tests via the production path

Browse Source 
Exercise Events_from_json -> ProcessCGMReading with real LID_CGM_DATA_G7
pump-logs events captured from a live account (device id redacted), asserting
sgv, egv-derived dateString, pump_event_id, and last-upload skip behavior.
The existing binary-fixture tests are kept alongside.
