@Cannibal No, they did not. That last scene is set in the immediate aftermath of the finale, not decades later.
In the show it is clearly and unambiguously stated that using the crystal shortens the lifespan of the user. It is why Fine is so opposed to Izetta using it. The more you use it, and the more power you release through it, the worse the effect is. Both Sophie and Izetta are aware of this, the former is just so hell-bent on revenge she does not give a fuck, while the latter would do anything to protect Fine.
It is this life-draining effect of the crystal that kills Sophie, and no, Izetta did not manage to magically avoid the effect. Sophie just had the disadvantage of using the stone longer, thus she had less to go on. She died when she desperately tried to match the magical output Izetta produced in that last part of their duel, the ludicrous amount of power she was trying to crystallise sucked her dry. Izetta survived only because she did not use the stone as long as her enemy, and thus had more to go on. But considering the level of usage in that last move, she probably drained most of her life force.
In short, no, they most certainly did not live happily ever after for the next 70+ years.
