Merged PR 2619: edeposit verifications container to staging

# Description

This PR turns the JSON documents of the verification container in sync into a table in staging. It also performs the necessary deduplication of records by ID and timestamp along the way.

I'm intentionally skipping proper documentation to unblock a colleague while I fetch the necessary knowledge to populate the schema docs properly. I pinky promise I won't forget and I'll come back and fix it.

# Checklist

- [X] The edited models and dependants run properly with production data.
- [ ] ~~The edited models are sufficiently documented.~~ __Nope, read above.__
- [X] The edited models contain PK tests, and I've ran and passed them.
- [X] I have checked for DRY opportunities with other models and docs.
- [X] I've picked the right materialization for the affected models.

# Other

- [ ] Check if a full-refresh is required after this PR is merged.
