v0.10.9 — SOC Max slider now reaches the device

Bugfix — same class of issue as v0.10.3

The SOC Max slider only updated the plugin's internal target. The Zendure's own `socSet` stayed at its default (100 %), so the device kept solar-charging past whatever the user configured.

Now `target_soc` changes are also published to `Zendure/number//socSet/set` — same fix pattern as we applied to `min_soc` in v0.10.3.

If you set SOC Max to 80 in the dashboard, the device will now actually stop charging at 80 %, regardless of source (solar, grid, manual).

Update

HACS → Update → reload integration. Then move the SOC Max slider once after the update so the new value is pushed to the device.
