ib: rework trade handling, take ib position sizes as gospel 

Instead of casting to `dict`s and rewriting event names in the
`push_tradesies()` handler, be transparent with event names (also
defining and piker-equivalent mapping them in a redefined `_statuses`
table) and types
passing them directly to the `deliver_trade_events()` task and generally
make event handler blocks much easier to grok with type annotations. To
deal with the causality dilemma of *when to emit a pos msg* due to
needing all of `execDetailsEvent, commissionReportEvent, positionEvent`
but having no guarantee on received order, we implement a small task
`clears: dict[Contract, tuple[Position, Fill]]` tracker table and (as
before) only emit a position event once the "cost" can be accessed for
the fill. We now ALWAYS relay any `Position` update from IB directly to
ensure (at least) the cumsize is correct (since it appears we still have
ongoing issues with computing this correctly via `.accounting.Position`
updates..).

Further related adjustments:
- load (fiat) balances and startup positions into a new `IbAcnt` struct.
- change `update_and_audit_pos_msg()` to blindly forward ib position
  event updates for the **the size** since it should always be
  considered the true gospel for accounting!
  - drop ib-has-no-position handling since it should never occur..
- move `update_ledger_from_api_trades()` to the `.ledger` submod and do
  processing of ib_insync `Fill` related objects instead of dict-casted
  versions instead doing the casting in
  `api_trades_to_ledger_entries()`.
- `norm_trade()`: add `symcache.mktmaps[bs_mktid] = mkt` in since it
  turns out API (and sometimes FLEX) records don't contain the listing
  exchange/venue thus making it impossible to map an asset pair in the
  "position sense" (i.e. over multiple venues: qqq.nasdaq, qqq.arca,
  qqq.directedge) to an fqme when doing offline ledger processing;
  instead use frickin IB's internal int-id so there's no discrepancy.
  - also much better handle futures mkt trade flex records such that
    parsed `MktPair.fqme` is consistent.
