Better success/error messaging after IOD submission

[johngribbin]

With the current implementation:

• User submits their IOD(s)
• Success/error messaging rendered at the bottom of the form

The problem with this is that the user may miss the feedback as the page returns to top of the form after submission. This is particularly evident in the SingleObservationForm component due to the length of the form.

A better solution would be perhaps be have a more pleasing user-experience like an animated pop-up modal.

@johngribbin This might be further improved by giving the user line-by-line feedback on success vs failure (perhaps clustering them until state changes from success/fail or fail/success).

I believe this would require more granular feedback from trusat-backend, but the success status could be returned in an array.

@interplanetarychris Agreed.
