Cleanup Figma files PCI

Tasks

[ ] Move the WIP canvas' wireframes up into the pre-checke-in and check-in Design pages in each file.

[ ] Make sure Check-in, Pre-Check-in, and LoROTA “Latest Design” pages are all updated with latest feature work that is “waiting for release” or “released”
- Reminder: DO NOT add “In progress” features to “latest design” pages until they are moved to “Waiting for release”
[ ] Update LoROTA “latest design” page to more closely match Check-in and Pre-Check-in formats
[ ] Simplify/optimize “latest design” pages in each file
- Remove unneeded components (headers, footers, need help)
- Use states where possible - for examples look at Unified and Check-in
- Incorporate user flow arrows - for examples look at Unified and Check-in
- Incorporate (general) annotations - for examples look at LoROTA. Note: we can use the feature pages for super specific annotations if we want to go more in-depth elsewhere
[ ] Update “About” pages to outline process/how we use these files - based on the process we outlined for Sketch + our new/updated steps
