Add Firebase logging to the upload process to categorize upload failures

## Problem

When uploads fail, we currently have very little insight into *why* they failed. We know network failures happen, but there may also be parsing failures or other types of failures we aren't aware of.

## Proposal

Add Firebase logging throughout the upload process that marks each distinct failure type, for example:

- Network failure
- Parsing failure
- Any other failure encountered along the way

Every instance of a failure should be logged with its type so we can see which failures actually occur in the field and how often.

## Goal

Use the collected data to determine what we actually need to solve for in the upload process, rather than guessing.
