Research direction

Start by reading the SNZB-02UL device definition and its exposed settings to see whether the e-ink clock format can be configured. The issue asks for a 12-hour time display but does not identify the relevant code or confirm that the device supports a setting for it. Done means establishing whether Zigbee2MQTT can expose this option and, if supported, making it available to users.
