Monitor PoE 802.3af/at power via native RouterOS scripts.

PoE power is critical for outdoor installations. This RouterOS script checks the PoE Ethernet port status every minute. In case of PoE power loss (switching to battery or DC), an alert log is generated. This allows triggering preventive actions such as reducing CPU frequency to save energy.
