Batch delete orders

[dcts]

This PR implements a feature where the user can cancel multiple orders at once, with a maximum capped at 8 orders.

Features (to test):

• accountHistory table rows now have a hover state for better UX
• batch deletion: select / deselect orders
• batch deletion: delete X orders
• single deletion should still work, the functionality is shown on hover state but is disabled once the user selects the order for batch deletion.

I appear to have COMPLETED orders in my open orders tab, but for some reason the json is returning PENDING

@nguvictor does the same happen when you try to delete such an order using the "Delete Single Order" button (on hover)? If yes I suggest to create a separate issue for this, as it seems to be a weird bug regarding the orders being displayed rather than related to the batch deletion feature.

Also the timeCompleted looks suspicious (1970), maybe this is a adex bug we should report in adex telegram chat?
