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

Phase 4: Retention & Cleanup

Status: Not Started Parent plan: PLAN.md Domain: backend

Objective

Implement automatic retention enforcement — prune old backups after each backup operation and on server startup.

Tasks

  • Task 1: Add Prune() method to backup engine
    • Delete backups exceeding retention count (keep N most recent)
    • Return count of pruned backups
  • Task 2: Call Prune after every CreateBackup (both manual and auto)
  • Task 3: Call Prune on server startup
  • Task 4: Clean up orphaned files (files in backup dir not in metadata)
  • Task 5: Log pruning results

Files to Modify/Create

  • internal/backup/engine.go — add Prune method
  • cmd/server/main.go — call prune on startup

Acceptance Criteria

  • Backups exceeding retention count are automatically deleted
  • Both file and metadata are removed during pruning
  • Orphaned files (no metadata) are cleaned up
  • Pruning runs after each backup and on startup
  • Pruning results logged
