Add an option to disable auto mantling while aiming down sights (ADS).

Sometimes when you're in a fight and trying to stay locked on a target, your character can accidentally climb over nearby obstacles just because you're close to them. This unintended mantling can completely throw off your aim and positioning, often costing you the fight.

Having the option to disable auto mantling while ADS would give players more control and prevent these frustrating moments, especially in close-range engagements where precision matters most.
