Improved `trade` WS Channel

⛔ Old “GRFQ” Behaviour

• quote_id belongs to the Maker who created the original quote.

• order_id belongs to the Taker who crossed the order book, and the Maker/multiple Makers who got filled.

Problem: The quote_id received in the messages may not belong to the User who is subscribed to the WS channel.

✅ New “OB” Behaviour

• quote_id now belongs to the User, regardless if he was a Maker or a Taker to the trade.

• order_id belongs to the Taker who crossed the order book, and the Maker/multiple Makers who got filled. (Unchanged)
