alexei.dolgolyov 3c9727162a fix: address review findings for backup management
- HIGH: Add sync.Mutex to backup Engine to prevent concurrent
  backup/restore operations
- HIGH: Restore uses io.Copy instead of ReadFile to avoid OOM on
  large databases
- HIGH: Send HTTP response before closing DB during restore, then
  perform destructive operations in a goroutine
- HIGH: Create pre-restore safety backup before overwriting database
- HIGH: Autobackup cron reschedules dynamically when settings change
  via callback pattern (same as DNS provider changes)

alexei.dolgolyov a9c7775bb7 feat: configuration backup management with manual and auto backup
Add backup/restore functionality for the SQLite database. Users can
trigger manual backups, configure automatic backups on an interval
with retention policies, list/download/delete backups, and restore
from any backup.

- Backup engine using VACUUM INTO (safe with WAL mode)
- Backup metadata tracked in DB, files stored in DATA_DIR/backups/
- Settings: backup_enabled, backup_interval_hours, backup_retention_count
- API: POST/GET/DELETE /api/backups, download, restore endpoints
- Autobackup via cron scheduler with configurable interval
- Retention: prune on startup, after each backup (manual and auto)
- Orphan cleanup: removes backup files without metadata on startup
- Restore: replaces DB and triggers graceful server shutdown
- Settings UI: /settings/backup with toggle, interval, retention config
- Backup list with download, delete, restore actions
- i18n: English and Russian translations
