add fee breakdown to broker order model

[djpnewton]

This give extra info so the UI can give a fee breakdown.

New example response from broker_order_validate/create API:

{
  "broker_order": {
    "base_amount": 10354, 
    "base_amount_dec": "0.00010354", 
    "base_asset": "BTC", 
    "date": "2022-10-26T03:31:26.343295", 
    "expiry": "2022-10-26T03:46:26.343314", 
    "market": "BTC-NZD", 
    "quote_amount": 3, 
    "quote_amount_dec": "0.03", 
    "quote_asset": "NZD", 
    "quote_fee": 1,             // see here
    "quote_fee_dec": "0.01", 
    "quote_fee_fixed": 100,     // and here
    "quote_fee_fixed_dec": "1", 
    "side": "ask", 
    "status": "created", 
    "token": "R0H4LE73Z4"

I've also run "flask-cli.sh db upgrade", would i need to run another script?
