Jannis e1e6d69d2c Use BLE device name, add hard poll timeout, tighten request timing ...

- Device name: coordinator now takes name=entry.title so the HA device card
  shows the actual BLE advertised name instead of "Xiaoxiang Smart BMS"
- Hard poll timeout: each poll is capped at (poll_interval - 3)s via
  asyncio.wait_for so a stalled poll can't bleed into the next cycle
- Request timeout: 5s → 3s (BMS should reply in <1s under normal conditions)
- Retry delay: 0.5s → 0.3s between retries
