Yeah tough to tell from pictures if it's safe or not. Have a local shop or carbon repair shop make a judgement in person if you want to be sure.
Technically, the bearing should be fully supported on the chamfer, and therefore the 52 inner diameter being slightly oversized shouldn't matter from a functional point of view. Now if the chamfered part is oversized you'll indeed have preload problems.
If you can't get a 52mm bearing to fully seat, you could pop a 51.8 bearing in there to see if the chamfer is correct(fit full headset, fork, stem, add preload. No play = correct seating), and then make decision to either have it reamed or just use a 51.8 bearing.
You have a picture of the full frame? Curious how it looks. Also what's the fork axle to crown? That's some wild tire clearance you mentioned.

. Seeing a 330g fork weight makes me wonder how they get it as light as an Open Mind fork for example, which is one of the skinniest fork I've ever seen.
