refactor: reorganize merged repo into clean directory structure

Reorganize the merged KNELServerBuild + PFVCluster repo:

  provisioning/    server provisioning (was ProjectCode/ +
                   Project-Includes/ + Project-ConfigFiles/)
  tests/           test suite (was Project-Tests/)
  perf/            Proxmox perf scripts (was top-level *.sh + scripts/)
  docs/            all documentation (was ProjectDocs/ + PROJECT.md +
                   K8S.md + TODO.md)
  dns-cluster-setup/  Technitium DNS cluster (unchanged)
  netinfra/        netinfra audit scripts (unchanged)
  switches/        switch configs (unchanged)
  vendor/          vendored KNELShellFramework (unchanged)

Update all internal path references from old directory names
(ProjectCode/, Project-Includes/, Project-Tests/) to the new ones
(provisioning/, tests/) across all scripts.
