v0.5.12: Compatibility with HA 2025.9.0 (not compatible with lower version)

What's Changed

• Fix renamed parameter by @erwin314 in #48

The pymodbus library renamed the parameter from slave to device_id. This diverges from the current Modbus spec (v1.1b), so integration code was updated accordingly.

Thanks to @erwin314 for noticing and fixing this one!
