monitoring: increase zigbee_sensor_stale threshold to 4 hours

Browse Source 
The 2-hour threshold was too aggressive for temperature sensors in
stable environments. Historical data shows gaps up to 2.75 hours when
temperature hasn't changed (Home Assistant only updates last_updated
when values change). Increasing to 4 hours avoids false positives
while still catching genuine failures.
