Does using actions like Reprieve/Iron Mine prevent the stronghold from activating or you're still considered to have paid the cost and therefore gain the extra conflict ?

Sacrificing the character is a cost of the ability, so if any effect prevents the character from being sacrificed you would not have paid the cost so the rest of the effect is unable to resolve.
