Fix user event matching 

Was using the wrong key before from our old code (not sure how that
slipped back in.. prolly doing too many git stashes XD), so fix that to
properly match against order update events with 'ORDER_TRADE_UPDATE'.

Also, don't match on the types we want to *cast to*, that's not how
match syntax works (facepalm), so we have to typecast prior to EMS msg
creation / downstream logic.

Further,
- try not bothering with binance's own internal `'orderId'` field
  tracking since they seem to support just using your own user version
  for all ctl endpoints? (thus we only need to track the EMS `.oid`s B)
- log all event update msgs for now.
- pop order dialogs on 'closed' statuses.
- wrap cancel requests in an error handler block since it seems the EMS
  is double sending requests from the client?
