TempSensorSim/TempSensor_max31865's temperature() now stores its reading on self.temp, so ATemperatureSensor's inherited AttributeChange (previously never triggered by anything) actually fires. TempSensorTask no longer keeps its own shadow copy of the reading - it registers its websocket-push callback on self.sensor directly and just drives the read each tick; server/brewpi.py's TC-feeding registration moved from sensor_task to sensor for the same reason. Priming read happens before registering the callback (not after) since all tasks are built synchronously at module level, before the asyncio event loop starts - registering first would fire on_temp_changed's asyncio.create_task() with no running loop.
