M2: full backup runs (database, config, data) with occ and cron

BackupService starts a run per location (database dump in one transaction, then config + data directory as a resumable file run), stores the state in ngb_runs after every step, locks a run while a step executes and records the snapshot. Previews, logs, updater backups and per-user cache/uploads are excluded (TreeWalker now supports patterns). BackupJob (every 5 min) starts the daily schedule and steps running runs with a short budget under web cron and a long one under system cron. occ: backup:run, backup:status, backup:list. Tested on NC34/PostgreSQL: first run 128 files / 1 GiB in 64 s (443 MiB uploaded to S3), unchanged second run 2 s / 0 bytes; a background run to SFTP completed through cron.php.
