[kyverno] Remove accidentally-committed Terragrunt-generated files

My previous commit (dacf3d9e, [kyverno] Import existing cluster state)
unintentionally picked up two Terragrunt-generated provider/locals
files from the meshcentral stack that a parallel worker had just
created. These are auto-generated on every plan/apply (marked
"Generated by Terragrunt. Sig:") and do not belong in the repo.

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

Files removed:
- stacks/meshcentral/cloudflare_provider.tf
- stacks/meshcentral/tiers.tf

No impact on the kyverno import work. State-level changes from
dacf3d9e (3 imports + 3 in-place updates) stand.

Updates: code-w97
