Adjust logbook stream consumer to handle new metadata

Wait for home-assistant/core#72394

Proposed change

Adjust logbook stream consumer to handle new metadata

The response format has changed to allow for metadata:

{
  'events': list[...],
  'start_time': float | None
  'end_time': float | None
  'partial': bool
}

events now contains the event stream
start_time is the start time of the query against the historical data (only present for historical data)
end_time is the end time of the query against the historical data (only present for historical data)
partial if present indicates more historical data is coming in a future message.

This will fix the Cannot read properties of undefined (reading 'when') error logbook data is empty for the live period.

I noticed it when I put the prerelease from an hour ago on my RPi3 (not powerful enough to run the dev setup for frontend so I have to wait for releases to test)

Besides that, logbook is quite responsive on my RPi3 test machine with the lowest quality micro sd card I have that I could get to boot for testing.
