Pull request overview

This PR updates the Shelly integration’s “Last restart” sensors to use Home Assistant’s new SensorDeviceClass.UPTIME so core can handle small drift/variance consistently.

Changes:

• Switch Shelly “Last restart” sensors from SensorDeviceClass.TIMESTAMP to SensorDeviceClass.UPTIME.
• Remove the Shelly-specific uptime drift helper (get_device_uptime) and its UPTIME_DEVIATION constant.
• Update Shelly device snapshots to reflect the new sensor device class.

File	Description
homeassistant/components/shelly/sensor.py	Uses SensorDeviceClass.UPTIME and computes last restart from utcnow() - timedelta(seconds=uptime) for REST/RPC sensors.
homeassistant/components/shelly/utils.py	Removes the no-longer-needed get_device_uptime helper and related imports.
homeassistant/components/shelly/const.py	Removes UPTIME_DEVIATION constant since drift handling is now in core’s UPTIME device class normalization.
tests/components/shelly/test_utils.py	Drops the unit test for the removed helper and cleans up unused imports.
tests/components/shelly/snapshots/test_devices.ambr	Updates snapshot expectations from timestamp to uptime device class.

Thanks!

Should we mark this as a braking change? Users may have templates using the device_class attr

I honestly think this one is fine to ship like this 👍
