✨ PostgreSQL support

[aaronleopold]

This PR piggybacks off of the work done by another (I became aware from #1167, thank you @sbeckstrand for your work) to add PostgreSQL support. There are a few seemingly unrelated changes in the mix, e.g. cargo chef in the Docker build, that on the surface seem fine but I have yet to meaningfully review. I may wind up pruning to keep this a more focused change, but we'll see.

I'm opening this PR a bit early in the hopes to get better visibility and help seeing it to the finish line. There are quite a few assurances I'd want via testing suites before really seriously considering a merge, since my immediate priority is ensuring existing or future SQLite-based installs do not break.

If you have time to help validate and/or improve, please feel free to base PRs into this branch.

You can provide a fully-resolved connection string via STUMP_DATABASE_URL or as separate vars:

• STUMP_DB_PASSWORD
• STUMP_DB_HOST
• STUMP_DB_PORT
• STUMP_DB_NAME
• STUMP_DB_USER

I can come back to this and make some contributions next week. I was mostly just exploring if I could easily plug in a psql connection setup but found that it required some changes to existing queries. Agree that it would make sense to heavily vet and add testing as I was really in an exploration phase of seeing if I could make it work. Then I stepped away the last week and a half for vacation 😅

Changes to the dockerfile can be reverted entirely (related to the github workflow changes already reverted). I was making attempts to improve the image build time, but no real improvement was made there.

This will go to nightly once #1315 is merged and released

I haven't encountered anymore postgres issues, doing a sanity pass on sqlite and then will merge this in
