The borg/restic/kopia engines all dropped to the dedicated backup user
via scattered 'sudo -E -u $docker_install_user'. Centralize that into a
single runBackupOp helper so the backup subsystem has one audit point and
the scoped sudoers needs only the (dockerinstall) drop rule.
Also:
- owncloud config heredoc tees -> runSystem (container-UID file)
- webui_display_logins: fix the broken 'command -v sudo sqlite3' guard
to 'command -v sqlite3' (body already runs sqlite3 via runInstallOp)

The apps SQLite DB ($docker_dir/$db_file) is owned by the manager user, so
read/write it AS the manager via runInstallOp instead of sudo (root). 48 call
sites across 28 scripts. In rooted this drops root->manager (correct owner);
in rootless it's the manager too (using runFileOp/dockerinstall here was the
'unable to open database' bug). The broken 'command -v sudo sqlite3' check
lines are left untouched (separate pre-existing issue).

Convert the backup/restore data-plane sudo calls (mkdir/chown/rm/sqlite3/tar/
gzip|tee) to runFileOp/runFileWrite. Rooted behaviour is identical (helper runs
sudo); rootless will run them as the unprivileged install user. Pilot subsystem
for the wider de-sudo. verify.sh's /tmp scratch ops left as-is (different
ownership domain, handled separately).

Reads files the backup user can't see from the host (container-owned, e.g.
Nextcloud's www-data data dir) by streaming them out THROUGH the container
(docker exec tar) — no host root, no host read perms, works rooted + rootless.
Extracts to staging as plain files so restic keeps full dedup + per-file
restore (not a piped tar blob); the live path is excluded from the snapshot.
Restore streams the staging copy back through a throwaway in-namespace
container that recreates the tree with the app's uid:gid.
Declared via a libreportal.backup.files compose label; Nextcloud (html, 33:33)
is the first to use it. Live capture failure falls back to stop-snapshot-start.

- Add libreportal.backup.db labels to the MariaDB/Postgres apps (nextcloud,
owncloud, bookstack, mastodon, invidious) so they back up live + consistent.
- If a declared dump cannot be taken (DB down, wrong path), the backup falls
back to stop-snapshot-start for that run instead of snapshotting torn data —
a misconfiguration degrades to 'safe with downtime', never to 'unsafe'.

Adds a logical-dump path so apps with a database can be backed up with zero
downtime and full consistency, instead of stopping the container.
- backup_db.sh: dump each declared DB live (mysqldump --single-transaction /
pg_dump / sqlite3 .backup), exclude the raw data dir from the snapshot, and
replay the dump on restore (pre-start rehydrate for sqlite, post-start load
for server engines).
- Databases are declared via a 'libreportal.backup.db' compose label so the
metadata travels with the app in the snapshot.
- New 'auto' strategy (now the default): live where a DB is dumpable or the app
is marked live-safe, stop-snapshot-start otherwise. Explicit stop/pause/live
remain as overrides.
- restic/borg/kopia adapters honour an exclude list on the live path.
- Manifest records the resolved per-app strategy and dumped databases.

Application backups were driven by one crontab entry per app, each offset by
id * CFG_BACKUP_CRONTAB_APP_INTERVAL minutes. That minute offset is written
straight into cron's 0-59 minute field, so past ~20 apps it overflowed into
an invalid entry that silently never fired, and the fixed spacing could not
serialize backups that ran longer than the gap.
Replace it with a single daily entry (`libreportal backup scheduled`) that
enqueues a backup task per enabled app. The existing systemd task processor
drains them serially — no minute overflow, real serialization, and backups
are now visible/cancellable in the Tasks UI. Per-app enable is read from
CFG_<APP>_BACKUP at schedule time instead of being mirrored into crontab.
Removes the stagger machinery (timing/setup/check/remove scripts), the
now-unused cron_jobs table + insert, and the CFG_BACKUP_CRONTAB_APP_INTERVAL
config knob and its WebUI field.
