Manage OpenPGP keys in the gpg engine from Terraform using the new
gpgvaultsecret provider, and create the first key ('pass') for passv.
- Add a gpg_key module wrapping the gpg_key resource; wire it through
vault_cluster (variable + module, depends_on the mount) and config discovery
(config.hcl group keyed <backend>/<name>, syd1 terragrunt input), mirroring
the *_secret_backend_role modules.
- Register the gpg provider in root.hcl (provider block + required_providers,
v0.1.0 from the terraform-unkin registry), alongside litellm.
- Add config/gpg_key/gpg/pass.yaml: an rsa-4096 key 'pass' in the gpg mount for
password-store. Private key stays in Vault; clients import the public key and
delegate decryption to gpg/decrypt/pass.
