Update lock/export experience beyond prototype to be sequential, include a final step

[aricka-lewis]

#3708 was the last iteration?

Based on research form lockdown and submit testing https://dovetailapp.com/data/Final-Report-for-Wiki-6YnsHmsj5OI3PlfiD2y5kR

I believe this is the current design, a prototype we tested. https://www.figma.com/file/6eVvo7JjvXiovGTR4BoVgK/CMS-eAPD-2022?node-id=7643%3A57370

This task is done when...

• [ ] Gather background around research work and what the process would be for the lock/export experience
• [ ] criteria 2

Add additional labels (design, dev, compliance, BUG, etc) and size before submitting.

If the issue is needed to complete prioritized work for the CURRENT SPRINT, add it to the "This Sprint" pipeline. Otherwise, all other issues will be automatically added to the unprioritized pipeline for prioritization in backlog refinement or sprint planning with Product.
