The docs still described Cloudflare as DNS + CDN in front of helsinki-a,
but that was dropped in #90 - pez.sh lives on Hetzner DNS via Terraform
now and records point straight at the origin. Updated README,
architecture, networking, getting-started and the nuremberg-a host doc
to match, and noted that pez.solutions still resolves via Cloudflare
outside Terraform.
Also fixed while I was in there:
- terraform/README: PagerDuty provider is ~> 3.32 (table said ~> 2.2),
and the B2 secret keys are backblaze_keyID/backblaze_applicationKey
- secrets docs: group_vars secrets file is .enc.yaml, dropped the
FreeBSD install steps, the long-gone .sops.yaml placeholder note and
the ANSIBLE_VAULT_PASS migration note, swapped the cloudflare_record
example for hcloud
- getting-started referenced ansible/scripts/sops-setup.sh which
doesn't exist
- added naveen.pez.sh to the subdomain tables and a note about the
DNS-only records (mail, minecraft, wow, public)
