chore: Add create_volume to swagger docs

[matheus23]

• Added a utoipa::path to the create_volume handler
• Updated flake so postgres works in NixOS
• Replaced ucan path dependencies with actual UCAN versions (@blaine this would still cause a runtime error, right? What's the github URL that I could depend on?)

Hm. We need a way to run kubo during tests.

Yeah, it's because the ucan:* "unscoped" bug in rs-ucan will result in proof chain validation failure. The "fix" I put in the vendored version was here: https://github.com/blaine/rs-ucan/tree/temporary-unscoped-fix (just a one line change), and I'm actually not sure the benefit of having a separate type for unscoped ucan: URIs so this may be the best overall fix (plus deleting related code)?

Anyhow, it's just on validating volume changes that things will fail until that issue gets resolved, or we can use a different resource (e.g. https://{domain}/api/account/{username}/*) instead of ucan:*

👍

Oh god. The formatting messed this diff up quite badly 😅
I actually didn't change anything - it just lined up the "diesel migration run" with the "diesel database setup" lines from the two versions of the file.
These scripts are literally unchanged!

[matheus23]

Ah - sorry for the huge diff in flake.nix. I actually have a nix formatter installed.

Might make more sense to just mock for CI?

Either way, can we get this merged so it's easier to build & run and work on a kubo testing strategy in a different PR?

[matheus23]

Yeah, let's merge.
