fix: move destructive aftermarket operations to sandbox

Moved bid, buy, and listing operations from prodClient to sandboxClient:
- add_backorder_request, delete_backorder_request
- place_auction_bid, place_backorder_auction_bid
- buy_expired_closeout_domain, buy_it_now
- set_for_sale
- set_afternic_confirm_action, set_sedo_confirm_action

These operations could cost real money or modify listings if run against production.
