Migrate the IB broker backend to use `ib_async` (the actively maintained
fork) instead of the now stale, original `ib_insync` lib.
Deats,
- update `pyproject.toml` dep: drop `ib-insync` pin, add
`ib-async>=2.1.0`.
- update lock file with `ib-async` and its new `aeventkit` dep (which
i guess replaces `eventkit`).
- obvi, change all `ib_insync` imports to `ib_async` across `.ib.*`.
- update docs and select internal comments referencing the original lib.
Also,
- drop unused `ledger_dict` init in `_flex_reports.load_flex_trades()`.
- fix union type annot style: `dict | None` -> `dict|None`.
- strip `.tzinfo` from `lastTimeStamp` in `normalize()` to avoid
IPC codec issues with `ib_async`'s `timezone.utc` injection.
- pop `'defaults'` from ticker data dict in `normalize()` to avoid
non-serializable `timezone` objects and warning-log in such
cases.

That is to be able to (eventually) introspect "ambiguous" contract sets
once we move to `ib_async` and its `returnAll: bool` now offered by
`IB.qualifyContractsAsync()`,

Also, tweak some type type annots to multline style in sibling mods.
Integrate `exchange_calendars` lib to detect market holidays in
gap-checking logic via new `.ib.venues.has_holiday()` helper!
The `.ib.venues` impl deats,
- add a new `has_holiday()` using `xcals.get_calendar()` and friends
for sanity checking a venue's holiday closure-gaps.
* final holiday detection-check is basically,
`(cash_gap := (next_open - prev_close)) > period`
- include `time_step_s` param to `is_venue_closure()` for boundary
tolerance checks.
* let's us expand closure-time checks to include `+/-time_step_s`
"off-by-one-`timeframe`-sample" edge case ranges.
- add real docstring to `has_weekend()`.
In `.ib.api` refine usage for ^ changes,
- move `is_venue_open()` call + tz-convert outside gap check
- use a walrus to capture `has_closure_gap` from `is_venue_closure()`
- add a `not has_closure_gap` condition to the
mismatched-duration/short-frame warning block to avoid needless warns.
- keep duration-based "short-frame" log as `.error()` but toss in a bp
so (somone can) umask to figure out wtf is going on..
* we should **never** really hit this path unless there's a valid bug
or data issue with IB/GFIS!
* keep recursion path masked-out just leave a `breakpoint()` for now.
Also some logger updates,
- import `get_logger()` from top-level `piker.log` vs `.ib._util` which
was always kinda wrong..
- change `NonShittyIB._logger` to use `__name__` vs literal.

With all detection logic coming from our new `.ib.venues` helpers
allowing use to verify IB's OHLC bars frames don't contain unexpected
time-gaps.
`Client.bars()` new checking deats,
- add `is_venue_open()`, `has_weekend()`, `sesh_times()`, and
`is_venue_closure()` checks when `last_dt < end_dt`
- always calc gap-period in local tz via `ContractDetails.timeZoneId`.
- log warnings on invalid non-closure gaps, debug on closures for now.
- change recursion case to just `log.error()` + `breakpoint()`; we might end
up tossing it since i don't think i could ever get it to be reliable..
* mask-out recursive `.bars()` call (likely unnecessary).
- flip `start_dt`/`end_dt` param defaults to `None` vs epoch `str`.
- update docstring to clarify no `start_dt` support by IB
- add mod level `_iso8601_epoch_in_est` const to keep track of orig
param default value.
- add multiline style to return type-annot, type all `pendulum` objects.
Also,
- uppercase `Crypto.symbol` for PAXOS contracts in `.find_contracts()`,
tho now we're getting a weird new API error i left in a todo-comment..

Add `loglevel` param propagation across the data feed and sampling
subsystems to enable proper console log setup in downstream (distibuted)
subactor tasks. This ensures sampler and history-mgmt tasks receive the
same loglevel as their parent `.data.feed` tasks.
Deats,
- add `loglevel: str|None` param to `register_with_sampler()`,
`maybe_open_samplerd()`, and `open_sample_stream()`.
- pass `loglevel` through to `get_console_log()` in
`register_with_sampler()` with fallback to actor `loglevel`.
- use `partial()` in `allocate_persistent_feed()` to pass
`loglevel` to `manage_history()` at task-start.
- add `loglevel` param to `manage_history()` with default
`'warning'` and pass through to `open_sample_stream()` from there.
- capture `loglevel` var in `brokers.cli.search()` and pass to
`symbol_search()` call.
Also,
- drop blank lines in fn sigs for consistency with piker style.
- add debug bp in `open_feed()` when `loglevel != 'info'`.

`open_brokerd_dialog()` and pass `loglevel` to all broker-backend
trade-dialog endpoints. This ensures all `open_trade_dialog()` will
receive the same level passed to the EMS, including the paper engine.
Deats,
- add `loglevel` param to `mk_paper_ep()` closure.
- pass `loglevel=loglevel` to all trade endpoint `open_context()`
calls and `mk_paper_ep()` invocations.
- change default `loglevel` in `open_ems()` from `'error'` to
`'warning'`.
- add `get_console_log()` calls for `'clearing'` and
`'piker.accounting'` at top of `open_brokerd_dialog()` to ensure those
dependent subsystems are console enabled given they're namely used by
the `brokerd` trade-dialog ep tasks.

Change most sub-modules to use `get_logger(name=__name__)` for
per-leaf-module `log` instances vs previous subpkg-level/shared refs.
Primary changes,
- import `get_[console_]logger()` from top-level `piker.log` across leaf
mods.
- change any `<subsys>._util.log` logger-instances as well (though this
approach should no longer be used since it masks the endpoint module's
emissions.
Also,
- add a defaulted `loglevel: str` param to all `open_trade_dialog()`
endpoints, anticipating it being passed in by `.clearing`-engine.
- call `get_console_log(level=loglevel, name=__name__)` in each trade
dialog ep to enable per-`brokerd`-backend console writing.
- drop `get_logger` from `.brokers.__all__` exports
- fix type annotations: `str|None` vs `str | None`
- add TODOs for,
* comments in `._util` about multi-subsys logging
* `.accounting.__init__` about console log setup

- add `with_tractor_log=bool(tll)` to `.get_console_log()`
- add assertion check for logger name.
- comment-out `tractor.trionics.collapse_eg()` context for now, pretty
sure we don't need it and it just ends up adding extra logging
overhead for no good reason (warnings on various `trio` internal

- change `piker.log.get_logger()` to use `pkg_name=` vs `_root_name=`.
- add `**tractor_log_kwargs` passthrough to both wrapper fns.
- add `with_tractor_log: bool` toggle to `.get_console_log()`.
- strip `'piker.'` prefix from logger names when present to avoid
newly added `tractor.get_logger()` warnings.
Surroundingly,
- add `subsys` import to `.clearing._ems` for log name
- update all `get_console_log()` calls to use `level=` kwarg
- add assertion checks for logger names in `_setup_persistent_emsd()`
Additionally,,
- fix all type annotations: `str|None` vs `str | None`.
- add multiline style to conditional in `.cli.services()`.
- drop unused `Optional` import from `._actor_runtime`.
- drop a few "blank lines" in various function sigs.

Add timeout-gated wait for `feed_is_live: trio.Event` before passing shm
tokens to `open_sample_stream()`; skip registering shm-buffers with the
sampler if the feed doesn't "go live" within a new timeout.
The main motivation here is to avoid the sampler incrementing shm-array
bufs when the mkt-venue is closed so that a trailing "same price"
line/bars isn't updated/rendered in the chart's view when unnecessary.
Deats,
- add `wait_for_live_timeout: float = 0.5` param to `manage_history()`
- warn-log the fqme when timeout triggers
- add error log for invalid `frame_start_dt` comparisons to

(like xauusd.cmdty) which never have vlm.. so it's nice to be rid of it

Fix annotation misalignment during backfill by switching from
client-computed indices to server-side timestamp lookups against
current shm state. Store absolute coords on annotations and
reposition on viz redraws.
Lowlevel impl deats,
- add `time` param to `.add_arrow()`, `.add_text()`, `.add_rect()`
- lookup indices from shm via timestamp matching in IPC handlers
- force chart redraw before `markup_gaps()` annotation creation
- wrap IPC send/receive in `trio.fail_after(3)` for timeout when
server fails to respond, likely hangs on no-case-match/error.
- cache `_meth`/`_kwargs` on rects, `_abs_x`/`_abs_y` on arrows
- auto-reposition all annotations after viz reset in redraw cmd
Also,
- handle `KeyError` for missing timeframes in chart lookup
- return `-1` aid on annotation creation failures (lol oh `claude`..)
- reconstruct rect positions from timestamps + BGM offset logic
- log repositioned annotation counts on viz redraw

Prevent `ValueError` from negative prepend index in
`start_backfill()` by checking buffer space before push
attempts. Truncate incoming frame if needed and stop gracefully
when buffer full.
Also,
- add pre-push capacity check with frame truncation logic
- stop backfill when `next_prepend_index <= 0`
- log warnings for capacity exceeded and buffer-full conditions
