kms: revert files accidentally bundled into the docs commit

The previous commit (81a7d804) swept in 23 unrelated working-tree files because
a rebase --autostash had left them staged in the index — including 4 files with
leftover git conflict markers (llama-cpp/main.tf, excalidraw/providers.tf,
url + wealthfolio .terraform.lock.hcl) from a stale 2026-05-25 stash, which is
invalid Terraform. Revert all 23 (terragrunt-generated backend/providers/lock
+ the llama-cpp markers) to their prior committed state; terragrunt regenerates
the generated files on the next run. Net effect of the docs commit is now just
the runbook doc.
