feat(secrets)!: Replace sops with agenix-rekey

sops-nix is tending to be fairly complex for our use-cases, which adds
difficulty to deploying, maintaining our wrapper module, keeping
".env.bin" files, etc.

agenix-rekey is a lot simpler.

notable in this commit is the `// { outputPath = ...; }` hack in
flake.nix. This is needed due to snowfall-lib otherwise butchering paths
such that agenix-rekey is unable to show us what secrets exist with
`agenix edit`, etc... companion to that is the lib.snowfall.fs stuff in
the secrets/default.nix file
