What

Add a new step to the "Initialize Terraform Backend" page documenting the need to request an S3 bucket policy size quota increase before deploying tfstate-backend.

Why

The reference architecture now uses explicit per-account ARNs instead of wildcard patterns in the tfstate-backend bucket policy. This follows the principle of least privilege but produces a larger policy that may exceed the default 20KB S3 bucket policy size limit. Users need to request a quota increase in the root account before deploying.
