[PhotoSync] Track upload/retry status of individual photos

[scolsen]

Right now, we batch process and batch retry photo uploads. This means we attempt to re-upload photos when one upload in the batch fails even if the other photos in question were successfully uploaded. Tracking upload status on a per-photo basis instead will allow us to avoid this duplicative work.

@rawbzz -- could use some UX help in figuring out the best way to indicate the status of individual photo uploads when you get a chance! Each photo upload can succeed/fail individually, and each submission may have one or more photo associated with it. lmk if I can provide more context, thanks!

@scolsen Yes! Do you have any screenshots of what currently happens right now?

@rawbzz This is lower priority, so removing milestone and bumping to P2. There are a few high priority questions tagged for you there when you a sec!

For posterity, this is the redesigned status screen which we're targeting for next week (minus the user names):

This code:

Is incorrect in that the calling function decided the retry behavior based on only one of the photo upload results. Reclassifying as bug.

@scolsen Adding as low priority for Iteration 27.
