fix(i18n): use 终止 instead of 中止 in zh-Hans approval dialog

中止 implies a temporary pause that can be resumed; 终止 means a
definitive end, which matches the English "Abort the turn" / "abort"
semantics of this action.

Update both the option label ("终止本轮") and the Esc key footer hint
("Esc：终止") in the approval/elevation widget.

Fixes #1273
