Final-review gaps in the system-config backup:
1. Scheduled (cron) backups skipped it — backupScheduleEnabledApps only queued
per-app backups, so the daily schedule never refreshed the system config (and
thus the backup-location creds could go stale). Now it queues a
`libreportal backup system` task (or runs inline on terminal-only installs),
and skips the reproducible libreportal app for consistency with backupAllApps.
2. No retention on system snapshots — they bypass backupAppStart's per-app forget,
so they accumulated unbounded. Add resticForgetSystem (tag system=config,
respects append-only + the same keep-* policy) + engineForgetSystem dispatcher;
backupSystemConfig now applies retention across all locations after snapshotting.
Verified with stubs: backupSystemConfig snapshots AND prunes on every location;
engineForgetSystem pairs with resticForgetSystem; scheduled createTaskFile call
matches the existing 3-arg signature.

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).

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.
