Tyler Goodlet 58da3ceecf Proxy heaven, choose one "preferred data client"
In order to expose more `asyncio` powered `Client` methods to endpoint
task-code this adds a more extensive and layered set of `MethodProxy`
loading routines, in dependency order these are:
- `load_clients_for_trio()` a `tractor.to_asyncio.open_channel_from()`
  entry-point factory for loading all scanned clients on the `asyncio` side
  and delivering them over the inter-task channel to a `trio`-side task.
- `get_preferred_data_client()` a simple client instance loading routine
  which reads from the users `brokers.toml -> `prefer_data_account:
  list[str]` which must list account names, in priority order, that are
  acceptable to be used as the main "data connection client" such that
  only one of the detected clients is used for data (whereas the rest
  are used only for order entry).
- `open_client_proxies()` which delivers the detected `Client` set
  wrapped each in a `MethodProxy`.
- `open_data_client()` which directly delivers the preferred data client
  as a proxy for `trio` tasks.
- update `open_client_method_proxy()` and `open_client_proxy` to require
  an input `Client` instance.

Further impl details:
- add `MethodProxy._aio_ns` to ref the original `asyncio` side proxied instance
- add `Client.trades()` to pull executions from the last day/session
- load proxies inside `trades_dialogue` and use the new `.trades()`
  method to try and pull a fill ledger for eventual correct pp price
  calcs (pertains to #307)..
