* Force live logbook to send an empty message to indicate no results
Since the sync task can take a while if the recorder is
busy, the logbook will appear to hang if we do not send
the first partial message even if its empty.
This work is in preparation for a higher database
commit interval where this issue is most obvious.
The historical only path did not have this issue because
it never had to wait for the db sync.
* update tests
* Initial orjson support take 2
Still need to work out problem building wheels

Redux of #72754 / #32153 Now possible since the following is solved:
ijl/orjson#220 (comment)
This implements orjson where we use our default encoder. This does not implement orjson where `ExtendedJSONEncoder` is used as these areas tend to be called far less frequently. If its desired, this could be done in a followup, but it seemed like a case of diminishing returns (except maybe for large diagnostics files, or traces, but those are not expected to be downloaded frequently).
Areas where this makes a perceptible difference:
- Anything that subscribes to entities (Initial subscribe_entities payload)
- Initial download of registries on first connection / restore
- History queries
- Saving states to the database
- Large logbook queries
- Anything that subscribes to events (appdaemon)
Cavets:
orjson supports serializing dataclasses natively (and much faster) which
eliminates the need to implement `as_dict` in many places
when the data is already in a dataclass. This works
well as long as all the data in the dataclass can also
be serialized. I audited all places where we have an `as_dict`
for a dataclass and found only backups needs to be adjusted (support for `Path` needed to be added for backups). I was a little bit worried about `SensorExtraStoredData` with `Decimal` but it all seems to work out from since it converts it before it gets to the json encoding cc @dgomes
If it turns out to be a problem we can disable this
with option |= [orjson.OPT_PASSTHROUGH_DATACLASS](https://github.com/ijl/orjson#opt_passthrough_dataclass) and it
will fallback to `as_dict`
Its quite impressive for history queries
