Removed the dead minikube manifests, container builds, and tooling shims left behind after the cv + docs migration to indri-native (#342). Deletes `argocd/{apps,manifests}/{cv,docs}/`, `containers/{cv,quartz}/`, and the `quartz`→`docs` mapping in `mise-tasks/container-version-check`. Bumps `docs.current-version` to `v1.16.0` (the blumeops release tag) now that the legacy nginx-base version pin is gone.
