OHI QA finding - File upload constraints

[michaelclement]

As a user, when I upload files I would like to receive explicit feedback/instructions so that I'm not confused by the form's behavior.

Context

Per findings 6 & 7 of this ticket, we have some questions surrounding upload behavior in two places. Namely

1. When requiring front and back of an insurance card, are we supposed to let the user select either property from either dropdown, or should/can we enforce a "one of each type" rule?
2. When uploading a large file, can we determine the file is too large prior to attempting the upload to the backend? Is that, in fact, what is happening?

Acceptance criteria

• Research is done to determine whether or not the existing behaviors are justified
  • Comments are added to this ticket to clearly document why/why not the behavior is justified
• If the behavior can/should be adjusted, large file uploads are stopped before time is spent sending data to the backend.
• If the behavior can/should be adjusted, front/back uploaders are modified to allow only one of each type
• If changes are implemented, they are visible in staging.
• @allanto-ah is notified to do QA sign off after implementation

All this work is done in this PR, but since OHI is in production I have to make a migration to make sure save-in-progress data with the old file upload structure gets properly handled.

Large file check is fixed in this other PR.

Once this hits staging I'll be able to throw this over to Allan for review.

@allanto-ah these changes are visible on staging and ready for you to take a look at. Thanks!
