LG-10301: Move IPP Address Search results components into package

[allthesignals]

🎫 Ticket

Move <InPersonLocations/> and other components into the address search package. This is another refactor/reorg step. No features are added.

🛠 Summary of changes

Three things are happening here:

1. I move all <InPersonLocations /> and downstream components (<LocationCollection/>, <LocationCollectionItem />) type definitions into the address-search types definition file.
2. Moved <InPersonLocations /> and downstream components (<LocationCollection/>, <LocationCollectionItem />) from @18f/document-capture to @18f/address-search package
3. Update affected imports accordingly.

📜 Testing Plan

Provide a checklist of steps to confirm the changes.

• Spot check locally. This is a refactor so tests should capture issues.

@allthesignals When I test locally (and hit api) with several real addresses, I keep hitting no post offices found in 50 miles on your branch. I don't think everything is wired up correctly. (It does work display/return addresses when I use mock data tho). I also notice that the address I entered is not what is displayed in the text below. Reach out on Slack if you want me to demo.

@gina-yamada and I looked into this and it seemed to have to do with an issue with local env configuration. The arcgis mock fallback was enabled, but the USPS fallback wasn't, meaning the arcgis mock was sending junk addresses (regardless of input) to USPS, which USPS rightly kicked back by returning no results.
