Add Zendure Smart Meter P1 integration

[NextNebula]

Proposed change

This PR adds a new integration for the Zendure Smart Meter P1, a local P1 smart meter dongle that reads energy data from a smart meter and exposes it via a local HTTP API. The integration uses a DataUpdateCoordinator to poll the device and exposes the reported values as sensor entities. It communicates with devices on the local network using the zendure-p1 library.
