Battery End-of-discharge SOC valid range is set to 12 - 20, instead of 0-20

Describe the issue

End-of-Discharge SOC valid range is currently set to 12-20%, while Huawei allows in Fusion Solar it to be set to as low as 0.

I believe this integration should follow Huawei's configuration options.

Please change the number.py line 83 to allow end of discharge to be set to 0.
