Subject: Refactor sensor API to support generic sensor types with configurable
 display precision
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replaced TemperatureSensor with a generic Sensor type that accepts sensor class, state class, unit, and display precision to support various sensor types. Added suggested_display_precision field to control decimal places in Home Assistant UI.
