ib: more trade record edge case handling

- 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.
