Subject: fix(wpcarro/ynab): Remove .skip-subtree

**TL;DR:**
- Delete half-baked packaging attempts (`job.nix`, `token.nix`).
- Ensure golang code compiles.
  - Some "packages" were being treated like "programs" presumably for
    debugging/testing purposes back when I was working on this. Make those
    behave like libraries.
  - Remove stale imports.
  - Fix syntax errors.
  - Miscellaneous other chores.
- Drop `shell.nix` and `use_nix` directive.
