Feature: Eastron SDM-630 Support + Float32 Decode (v1.1.5)

- inverters.py: data_type Feld in Sensor (uint16/uint32/float32)
  + SDM-630 Definition (16 Sensoren: U/I/P L1-L3, PF, Freq, kWh)
  + read_ranges: [(0, 76)] — alle Sensoren in einem Batch
- modbus_client.py: Float32 IEEE 754 Decode via struct.unpack
  (SDM-630 liefert Floats, Growatt liefert skalierte Integer)
- index.html: "Wechselrichter" → "Gerät" — Add-on unterstützt
  jetzt beliebige Modbus-Geräte, nicht nur Wechselrichter
