v0.3.2-beta.1

Fixed

• Card: entity_detail inline/tooltip now shows unit_of_measurement alongside the HA state value (e.g. 85 % instead of 85 for battery sensors)
• Coordinator: entities with device_class: battery now use their own state as the battery level, so mobile companion app battery sensors are correctly tracked and displayed in the card
• Coordinator: offline_since now reflects state.last_changed when the entity was already in a bad state before the coordinator first polled it — offline duration shown in the card is accurate after HA restarts
