Some sanoid packages (e.g. on Ubuntu 26.04) don't ship /etc/sanoid, so the
config template failed with 'Destination directory does not exist'. Create
the directory explicitly, and copy the packaged sanoid.defaults.conf into
it (sanoid requires it beside sanoid.conf) so the first timer run succeeds.

Implements the two decoupled backup streams from docs/06 as an idempotent
Ansible role wired into the host playbook:
- Files: sanoid takes/prunes ZFS snapshots per policy (sanoid_datasets) on
its packaged timer; syncoid replicates offsite (heleos-zfs-offsite),
enabled only when zfs_offsite_target is set.
- DB: heleos-db-backup (nightly systemd timer) walks the deployments dir and
dumps each DB-backed site via `docker exec mariadb-dump` into
db-backups/<customer>/<site>/{daily,weekly,monthly} with rotation
(automysqlbackup-style, adapted for the containerized DB; MYSQL_PWD keeps
the password out of the process list). heleos-db-offsite rsyncs offsite
when db_offsite_target is set.
Streams and schedules are configured in group_vars/all.yml; offsite is
opt-in via the two target vars. Updates doc 06 (implementation note), the
ansible README, and CLAUDE.md status. YAML + templates validated by render.
