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.
