- replaced CERTBOT_DNS_API_TOKEN with CLOUDFLARE_API_TOKEN everywhere
- introduced generic sys-dns-cloudflare-records role for managing DNS records
- added sys-dns-hetzner-rdns role with both Cloud (hcloud) and Robot API flavors
- updated Mailu role to:
- generate DKIM before DNS setup
- delegate DNS + rDNS records to the new generic roles
- removed legacy per-role Cloudflare vars (MAILU_CLOUDFLARE_API_TOKEN)
- extended group vars with HOSTING_PROVIDER for rDNS flavor decision
- added hetzner.hcloud collection to requirements
This consolidates DNS management into reusable roles,
supports both Cloudflare and Hetzner providers,
and standardizes variable naming across the project.
