Jannis 03b63c476a Add request retries and nominal capacity override number entity ...

Retries (bluetooth_handler):
- request() now retries up to 3× with 0.5s pause between attempts
- Tries Write With Response first, falls back to Write Without Response
  automatically if the characteristic rejects it — handles both BMS variants

Number entity (number.py):
- "Nominal Capacity (Override)" lets user correct a stale BMS capacity value
  (e.g. after a cell upgrade) without PC software
- Value is restored across HA restarts via RestoreEntity
- Immediately patches coordinator.data so the sensor reflects it without
  waiting for the next poll
