[meshcentral] Remove accidentally-committed Terragrunt-generated files

My previous commit (c0ac24a5, [meshcentral] Import existing cluster
state + PVC) unintentionally committed two Terragrunt-generated
provider/locals files. These are auto-generated on every plan/apply
(marked 'Generated by Terragrunt. Sig:') and do not belong in the
repo. Mirrors 3e11bd1b which did the same cleanup for kyverno.

Removes from tracking only — files remain on disk so concurrent work
is unaffected.
