Jannis dcc528b96a Add global BLE lock + faster timeouts for multi-device reliability

Root cause: 3 BMS devices fighting for 3 ESPHome proxy connection slots
simultaneously, causing 80% timeout failures and 22s+ poll times.

Fixes:
- Add shared asyncio.Lock so only one BMS polls at a time — eliminates
  proxy slot contention entirely
- Pass ble_device_callback to establish_connection so retry attempts
  get a fresh BLEDevice (handles proxy path changes)
- Reduce command timeout 5s -> 3s, retries 3 -> 2 (BMS responds in
  <200ms when connection is clean)
- Reduce establish_connection max_attempts 3 -> 2 (fail fast, retry
  next cycle instead of blocking 25s)
- Fixed poll timeout to 15s (was poll_interval-5=25s)

Expected: polls complete in 2-5s instead of 22s, ~95%+ success rate.
