docs: fix KDoc inconsistencies in transport files

- BleReconnectPolicy: clarify maxFailures param documents Int.MAX_VALUE
  disables the give-up path; remove misleading 'give up permanently'
- StreamTransport.onDeviceDisconnect: fix confusing 'wait for it to come
  back' sentence in KDoc summary
- BleRadioTransportTest: import VerifyMode instead of fully-qualifying
