asset lod: fix high-res images (#4198)

high-res images are busted currently, we weren't doing `Math.min` before
https://github.com/tldraw/tldraw/pull/4069 and now it's limited by the
natural width of the image which is actually at odds with what's been
uploaded.

## for separate PR
...actually, now that i think about it, this code isn't doing any
resizing anymore - the server has the high-res images but we're only
recording it as a smaller image:
```
if (isFinite(maxImageDimension)) {
	const resizedSize = containBoxSize(size, { w: maxImageDimension, h: maxImageDimension })
	if (size !== resizedSize && MediaHelpers.isStaticImageType(file.type)) {
		size = resizedSize
	}
}
```

### Change type

- [x] `bugfix`
- [ ] `improvement`
- [ ] `feature`
- [ ] `api`
- [ ] `other`
