Bastian de Byl c184099b2d refactor(backup): remove duplicate direct-to-S3 stage
A host-to-iDrive S3 stage was added here and is now removed. It would
have written the same data into the same `backup-all` bucket that the
TrueNAS cloud-sync task already fills -- duplicate storage, two writers
to one prefix, for no additional coverage.

Offsite to business-owned storage was already solved: the rsync feeds
/mnt/glacier/skudakcloud and TrueNAS cloud-syncs that to Skudak's own
iDrive e2 account. The earlier note in skudak/cloud.yml proposed adding
S3 *and then dropping the rsync* -- replacement, not addition -- and
building both was a misreading of it.

If offsite is ever moved onto this host it must REPLACE the rsync, not
run beside it. Settle first whether the TrueNAS -> iDrive leg is
independently verifiable; keeping this chain means trusting it.

Also removes the now-orphaned /etc/backup_s3 credential file.

Bastian de Byl bc110ce69e back up Gitea + Skudak app data; drop PartKeepr and Pi-hole
Extends the Nextcloud backup machinery rather than adding a second
mechanism. cloud-backup.sh.j2 gains three guarded options, all no-ops for
the existing callers:

  backup_podman_user  Gitea runs rootless under `git`, not `podman`
  backup_db_type      postgres (Gitea) and mysql (BookStack) alongside
                      mariadb; each engine's completion trailer differs,
                      and grepping for the wrong one fails every run
  backup_sqlite_dbs   `sqlite3 .backup` for live WAL-mode SQLite, gated on
                      `pragma integrity_check` before promotion -- rsync
                      is either stale (no -wal) or torn (with it)

New instances: gitea-debyl, skudak-gitea, bookstack, partsy-skudak. The
alert handler is rendered once and shared, so its wording is now generic
rather than per-product; TAG stays nextcloud-backup because an external
Graylog rule matches on it.

`apply:` on the includes is load-bearing -- tags on a dynamic
include_tasks do not reach the tasks inside it.

Business data (skudak-gitea, bookstack, partsy-skudak) goes to TrueNAS
and on to Skudak's own iDrive account; the personal bucket's
/skudak*/** excludes are permanent, not a stopgap.

Removals: PartKeepr is superseded by Partsy, and its teardown never
finished -- it targeted /etc/systemd/system/podman-partkeepr*.service,
wrong prefix and wrong scope, leaving enabled user units in failed state.
Pi-hole's role was already orphaned (absent from deploy_home.yml); its
port 53 rule went with it after confirming nothing listens there.

Bastian de Byl 6e99794d0f restore full dump flags; stop spurious alerts claiming FAILED
mariadb-upgrade --force has now been run against both instances and repaired
the system tables, so --routines and --events no longer abort the dump.
Restore them for completeness. Both verified: rc=0 with a clean completion
trailer, and both Nextcloud instances report installed with unchanged table
counts afterwards.

The upgrade still exits non-zero on these containers because it cannot create
the `sys` schema: /var/lib/mysql is owned by daemon rather than mysql, so
mysqld may not create top-level databases. `sys` is diagnostic only and
unused by Nextcloud, but the same permission would block creating any new
database, so it is recorded in the template comment.

The alert handler claimed FAILED in its subject line regardless of what the
unit actually reported, so starting it by hand mailed out a failure notice
for a run that succeeded. Derive the subject and log line from the real
Result, and emit status=spurious rather than status=failed so such triggers
cannot match a Graylog alert rule keyed on genuine failures.

Bastian de Byl 0ab423ca55 harden nextcloud backups: db dumps, alerting, drift fix
The data-only rsync left no way to restore a working instance: mysql/ and
config/ were never backed up, so a recovery would have files but no shares,
users or metadata. Dump the database before syncing files (a DB older than
the files is repairable with occ files:scan; a newer one references blobs
that never made it into the backup) and ship config/ alongside it.

Capture the --chmod=Du=rwx,Dgo=rx flag that had been hand-added to the
deployed skudak-cloud script. It was outside git, so every deploy silently
reverted it. It now lives in backup_rsync_extra_args.

Add OnFailure= alerting. The units failed silently before, which is how an
iDrive sync failure sat unnoticed since May. msmtp rather than the esmtp
already installed: the OpenSRS relay is port 465 (implicit TLS) and libesmtp
only speaks STARTTLS.

Exclude nextcloud.log* from the sync and cap log_rotate_size. skudak-cloud
was running at loglevel 0 and had written a 64 GB log that was being rsynced
and pushed to S3; set it to 2 to match the home instance.

Stagger the timers (04:00 / 04:30) so both finish before the 05:00 TrueNAS
snapshot task, and bound TimeoutStartSec so a wedged rsync cannot leave the
unit activating forever and skip every subsequent trigger.

Bastian de Byl 43fbcf59a5 add n8n workflow automation and fix cloud backup rsync
- Add n8n container (n8nio/n8n:2.11.3) with Caddy reverse proxy at n8n.debyl.io
- Add --exclude .ssh to cloud backup rsync to prevent overwriting
  authorized_keys on TrueNAS backup targets
