Merge branch 'sinexcel_multiinveters_configurtaion' into main

Introduce per-cluster Configuration page (V2) for installations 790, 839
(Growatt + Sinexcel pilot). All other installations continue using the
original SodistoreHomeConfiguration unchanged via an installation-id gate.

V2 highlights:
- Per-inverter / per-cluster Battery Limits (foldable accordions)
- Default current = slotCount * 95A from preset
- Dynamic Pricing block under LoadPriority (Off / Spot Price / TOU)
- Wire format: Devices.InverterN.Clusters.ClusterN.{BatteryCount, MaxCharging/DischargingCurrent}, PvCount

Backend Configuration DTO keeps legacy flat fields for V1 backward compat;
audit log + UDP send both use JsonIgnoreCondition.WhenWritingNull.

Pilot validation on installation 790 + 839 before V2 becomes the default.
