Vincent Ambo 3a410a78df feat(ops/secrets): Make (encrypted) secrets part of the tree
Currently in NixOS configuration using agenix secrets there is no
build time validation of secret paths - things fail at runtime (system
activation).

To prevent that, this CL makes the secrets part of the tree based on
the same configuration file used by agenix itself.

This guards against:

* agenix secrets.nix definition for a non-existent file
* age.secrets value in a NixOS config for a non-existent secret
