fix(nix): add git and openssh to systemd service PATH for purgatory sync

ngit-grasp requires git and ssh binaries in PATH to clone repositories
during purgatory sync operations. Without these in the systemd service
environment, all git fetch operations fail with 'No target repo found'.

This fix adds git and openssh to the service PATH via systemd's
Environment directive, allowing purgatory to successfully clone
repositories from remote URLs.
