Rewrite order ctl tests as a parametrization 

More or less a complete rework which allows passing a detailed
clearing/fills input and allows for *not* rebooting the runtime / ems
between each position check.

Some further enhancements:
- use (unit) fractional sizes to simulate both the more realistic and
  more "complex position calculation" case; since this is crypto.
- add a no-fqme-found test.
- factor cross-session/offline pos storage (pps.toml) checks into
  a `load_and_check_pos()` helper which does all entry loading directly
  from a provided `BrokerdPosition` msg.
- use the new `OrderClient.send()` async api.
