Deleting a card created no Activity (only archiving did), so the
Activities.after.insert outgoing-webhook hook never fired on real deletion.
Added a deleteCard Activity in the Cards before.remove hook and in the two REST
card-delete endpoints (which use Cards.direct.removeAsync and bypass the hook),
so an outgoing webhook is now sent on card deletion, consistent with other
events. (#2950: board/list/swimlane deletion already emit removeBoard/removeList/
removeSwimlane activities, so those webhooks were already present.)
