@bklebe this scaffolding is ready for review now. I don't expect the details like the schema to be fully correct yet, it is to have something in place for tickets.

[nlwstein]

I'm glad that I am reviewing this after I actually used it to get the S3 part working because I feel confident in saying this worked well and I ran into no issues while using the foundational pages here. 🚀

Suggested change

	timestamps()
	timestamps(type: :utc_datetime)

and migration update.

[meagharty]

Since we had a few dependent PRs (#984 is branched off of this, this PR was branched off another), I moved this into a new PR.
