Price band protection for crypto trading

Price band protection introduced to prevent trades from executing outside a predefined percentage range around an external reference price.

Order Validation Updates
Orders that would execute at an invalid price will be automatically canceled.

Reject Reasons Updates
Orders may now be canceled with the following reasons:

1. canceled due to reference price stale – Order was canceled because the reference price used for price band validation was outdated.
2. canceled due to price band protection. Index price: <index_price> Price band: <price_band>%, Rejected price: <maker_order_price> – Order was about to execute at a price exceeding the allowed range
