Front wheel twist and move in dropouts when braking or on aggressive turns
A lot of forks do this because the axle path is wrong. It needs to open forward to resist ejection force by disc brakes. The downward path was chosen to do the same for rim brakes. Many companies have made this switch, but not enough.
High-quality internal-cam QRs apply the most clamping force of any type. The simple answer is get any Shimano skewer. A better answer to this question would feature actual cam math, and I would welcome that, but barring that the above is usually a good starting place.
Dropout alignment can be a component of this problem as well. Being an aluminum fork, you'd have to replace the fork to do anything about it though if there was significant misalignment.
