Are the raw photos manipulated or are they just the original 1s and 0s unedited?

I think your average camera does not have the option to save RAW files. It seems somewhat common even outside professional equipment, though.

Could upload it’s hash

Yes, exactly. However, this would only prove that the image (and metadata like GPS coordinates) existed at that particular point in time. That would add a lot of credibility to, say, dashcam footage after a collision. It's curious that misinformation has become a major issue in the public consciousness, at a time when we have far better means of credibly documenting facts, than ever before.

But it would do little to add weight to images from, say, war zones. Knowing that a particular image or video existed at a particular point in time would rarely allow the conclusion if it was real or misinformation. In some cases, one may be able to cross-references with independent, trustworthy sources, like reporters from neutral countries or satellite imagery.

Creating a tamper-proof camera is a fool's errand. The best you can do is tamper-resistant. That may be enough if the camera can be checked by a trustworthy organization and does not leave its control for long. But in such a scenario you would rarely need that, and it's not the usual scenario. The price would be very high. Fakes that do pass muster will be given more credibility.
