Add Bulk Order Management with "Clear All" Functionality

"Clear All" Button for Mass Limit Order Cancellation.

Users need a quick and efficient way to cancel all pending limit orders simultaneously rather than having to close each order individually. This feature would include a "Clear All" button or similar bulk action functionality that allows traders to instantly cancel all pending limit orders across their connected accounts with a single click, potentially with a confirmation dialog to prevent accidental cancellations. This tool would be particularly valuable during volatile market conditions or when traders need to quickly clear their order book to reassess market conditions, significantly improving order management efficiency and reducing the time required for portfolio adjustments.
