infra: add kubectl + authentik providers across 6 stacks

Provider declarations were applied across freshrss, linkwarden,
navidrome, openclaw, tandoor, vault in prior sessions; lock files
regenerated for the 4 stacks where init had run. Commits the WIP so
downstream Terraform plans can proceed.

- kubectl (gavinbunney/kubectl ~> 1.14): kubernetes_manifest panic
  workaround for Kyverno CRDs (beads code-e2dp)
- authentik (goauthentik/authentik ~> 2024.10): used where stacks
  manage their own Authentik objects
