About time we tidy'd a buncha status logging in this backend..
particularly for boot-up where there's lots of client-try-connect poll
looping with account detection from the user config.
`.api.Client` pprint and logging fmt improvements:
- add `Client.__repr__()` which shows the minimally useful set of info
from the underlying `.ib: IB` as well as a new `.acnts: list[str]`
of the account aliases defined in the user's `brokers.toml`.
- mk `.bars()` define a comprehensive `query_info: str` with all the
request deats but only display if there's a problem with the response
data.
- mk `.get_config()` report both the config file path and the acnt
aliases (NOT the actual account #s).
- move all `.load_aio_clients()` client poll loop requests do
`log.runtime()` statuses, only falling through to a `.warning()` when
the loop fails to connect the client to the spec-ed API-gw addr, and
|_ don't allow loading accounts for which the user has not defined an
alias in `brokers.toml::[ib]`; raise a value-error in such cases
with a message indicating how to mod the config.
|_ only `log.info()` about acnts if some were loaded..
Other mod logging de-noising:
- better status fmting in `.symbols.open_symbol_search()` with
`repr(Client)`.
- for `.feed.stream_quotes()` first quote reporting use `.runtime()`.
- timestamps came as `'date'`-keyed from 2022 and before but now are
`'datetime'`..
- some symbols seem to have no commission field, so handle that..
- when no `'price'` field found return `None` from `norm_trade()`.
- add a warn log on mid-fill commission updates.
