B-23280: Update document viewing zoom scale

[traskowskycaci]

Agility ticket

• Lots of trial and error to add a nicer looking default zoom scale based on the dimensions of an image
• Zoom scale of 10% up to 200%, with default being 100%
• Sending the current zoom percentage to the UI to be displayed next to the Zoom in and Zoom out buttons in the document viewer
• Cleaning up references to Photo360Viewer. I found a bug in this code, and determined we no longer need to even use it, as we can simplify and use the PhotoViewer. The use cases of a photo with the dimensions for triggering the use of Photo360Viewer would be rare, and not an image size that should be uploaded as part of our business process. If one is uploaded, we can still render it via PhotoViewer

Works great, BUUUUUTTTT. Going backwards it doesn't do the 10,25,50,75,100 order.

Like zooming in you go:
110, 125, 150, 175, 200

But out is:
100 -> 75 -> 50 -> 25 -> 10

---

Also I think we need to take out my portion of the AC here:

(Eg if you click zoom in 3 times, you will be at 150%, but if you zoom out, it should go to 140%

I believe I was incorrect with this example. What you currently have is definitely better

Meets AC, good for POA
