The nixpkgs-unstable channel's programs.sqlite was used to identify
packages producing exactly one binary, and these automatically added
to their package definitions wherever possible.
Previously, the console portion of ZITADEL used Buf remote plugins to generate
sources. This resulted in the hash for the protobuf generated code changing
whenever the remote builders changed. This change patches the console
configuration to use local plugins from Nixpkgs instead of remote ones, to
ensure the output isn't influenced by remote changes.
