nodito: de-Uptime-Kuma the ZFS and NUT playbooks, extract templates
These two are host-specific by design - nodito is a pet, not cattle - so they
stay playbooks rather than becoming roles. But they had rotted.

De-Kuma, following the pattern of the six service roles:

  Both plays opened with an assert on uptime_kuma_username/password, which were
  removed from the vault, so both failed before doing anything. Dropped that,
  the two embedded Python monitor-creation scripts, and their /tmp cleanup.
  Kept every check, threshold and systemd timer - those are the durable part.

  Reporting is now generic: `healthcheck_push_url` goes into the unit as
  Environment=HEALTHCHECK_PUSH_URL and the script reads ${HEALTHCHECK_PUSH_URL:-},
  treating empty as normal rather than an error. The exit code is the real
  answer; systemd keeps it. Both scripts now also report status=down on failure
  instead of only going silent. Live push URLs harvested into the vault so
  nothing observable changes for ZFS.

Three live bugs found while check-diffing:

  1. 32_zfs would have DE-REGISTERED the Proxmox storage. `pvesm remove` was
     gated on the storage existing and `pvesm add` on it NOT existing - mutually
     exclusive - so a real run removed the proxmox-tank-1 entry backing every VM
     and never put it back. It would also have dropped `mountpoint /var/lib/vz`,
     which the live entry has and `pvesm add` does not set. Registration is now
     add-only.

  2. zfs_disk_1 named ata-...WX11TN0Z, a disk no longer in the machine. The live
     mirror is WX120LHQ + WX11TN2P; a leg was replaced and the repo never caught
     up. Inert behind `when: zfs_pool_exists.rc != 0`, but wrong on any
     disaster-recovery run. This is the seventh instance of an identifier
     written down once whose hardware later moved.

  3. 34_nut has NEVER been applied to nodito - no /etc/nut file carries the
     "Managed by Ansible" marker; they were written by hand in January 2026. The
     vault held the literal CHANGE_ME_TO_SECURE_PASSWORD, so applying it would
     have overwritten a working upsd/upsmon auth pair with a placeholder and
     restarted NUT, leaving the hypervisor's UPS unable to trigger a clean
     shutdown on mains loss. The Kuma assert was the only thing stopping that,
     so removing it without a replacement would have armed the gun: there is now
     an explicit assert that refuses to run on the placeholder. The real
     password is in the vault and `Configure upsd users` check-diffs clean.

  Templates reconciled with the live files first, so applying 34_nut is close to
  a no-op: added `maxretry = 3` to ups.conf and OFFDURATION / RBWARNTIME /
  NOCOMMWARNTIME / FINALDELAY plus quoted POWERDOWNFLAG to upsmon.conf. The only
  substantive additions left are the NOTIFYMSG/NOTIFYFLAG syslog lines.

  /usr/local/bin/ups-heartbeat.sh on the box is an orphan - mode 0644, not
  executable, referenced by no unit and no cron entry - but its push token
  belongs to a monitor that still exists and answers, so that monitor has had no
  heartbeat since January. Harvested as healthcheck_push_urls.ups; applying this
  play is what will finally feed it.

Finish the host_vars migration:

  infra/nodito/nodito_vars.yml was byte-identical to host_vars/nodito/main.yml.
  Deleted it, moved nodito_secrets.yml to host_vars/nodito/vault.yml, and
  stripped the dead vars_files entries from all three playbooks.

Extract the 13 inline `content: |` blocks to infra/nodito/templates/, pulled via
a YAML load rather than retyped. 681+582 lines become 313+344 plus templates.
Ownership parity against HEAD checked mechanically: no owner/group/mode drift on
any surviving task.

Neither playbook has been applied. ZFS play 2 check-runs failed=0 with two
changes: the script rewrite (the deployed one is a hand-edited DEBUG VERSION
with `set -x`) and the Environment line.
