Finalize Export messaging and behavior

[sssoleileraaa]

Description

Now that we have end-to-end exporting of files in the client, we need to finalize messaging and behavior.

Resources:

• zeplin screens
• invision flowchart
• invision interaction model
• PR that integrated export functionality
• Export demos (poor video quality)

Related to messaging we need to finalize:

• Add "Export Successful" message #556
• Don't close Export Dialog when the user clicks outside of it #557

[sssoleileraaa]

Separated UI styling in its own Issue: #560 so that it is not blocked by changes in wording or behavior.

We also need to finalize messaging around: MULTIPLE_PRINTERS_CONNECTED and MULTIPLE_DRIVES_CONNECTED

[sssoleileraaa]

Here is placeholder messaging for MULTIPLE_DRIVES_CONNECTED (for now don't include the line about drive names until we add support/documentation for this)

Zeplin Draft, from 24 Nov meeting to agree on messaging and basic flow.

Text may be copy/pasted from draft. Because there is not a specific GH Issue for content, alone, I will keep the canonical source-of-truth in copyediting for these windows, in Zeplin.

...also see This UX Repo Issue as canonical source-of-truth for allthings Export.

Yup... me to do!

(This issue is quite dated an no longer useful as an organizing epic; we can track/implement iterative improvements independently. Closing this issue.)
