feat: Add automated bookmark backup feature (#2182)

* feat: Add automated bookmark backup system

Implements a comprehensive automated backup feature for user bookmarks with the following capabilities:

Database Schema:
- Add backupSettings table to store user backup preferences (enabled, frequency, retention)
- Add backups table to track backup records with status and metadata
- Add BACKUP asset type for storing compressed backup files
- Add migration 0066_add_backup_tables.sql

Background Workers:
- Implement BackupSchedulingWorker cron job (runs daily at midnight UTC)
- Create BackupWorker to process individual backup jobs
- Deterministic scheduling spreads backup jobs across 24 hours based on user ID hash
- Support for daily and weekly backup frequencies
- Automated retention cleanup to delete old backups based on user settings

Export & Compression:
- Reuse existing export functionality for bookmark data
- Compress exports using Node.js built-in zlib (gzip level 9)
- Store compressed backups as assets with proper metadata
- Track backup size and bookmark count for statistics

tRPC API:
- backups.getSettings - Retrieve user backup configuration
- backups.updateSettings - Update backup preferences
- backups.list - List all user backups with metadata
- backups.get - Get specific backup details
- backups.delete - Delete a backup
- backups.download - Download backup file (base64 encoded)
- backups.triggerBackup - Manually trigger backup creation

UI Components:
- BackupSettings component with configuration form
- Enable/disable automatic backups toggle
- Frequency selection (daily/weekly)
- Retention period configuration (1-365 days)
- Backup list table with download and delete actions
- Manual backup trigger button
- Display backup stats (size, bookmark count, status)
- Added backups page to settings navigation

Technical Details:
- Uses Restate queue system for distributed job processing
- Implements idempotency keys to prevent duplicate backups
- Background worker concurrency: 2 jobs at a time
- 10-minute timeout for large backup exports
- Proper error handling and logging throughout
- Type-safe implementation with Zod schemas

* refactor: simplify backup settings and asset handling

- Move backup settings from separate table to user table columns
- Update BackupSettings model to use static methods with users table
- Remove download mutation in favor of direct asset links
- Implement proper quota checks using QuotaService.checkStorageQuota
- Update UI to use new property names and direct asset downloads
- Update shared types to match new schema

Key changes:
- backupSettingsTable removed, settings now in users table
- Backup downloads use direct /api/assets/{id} links
- Quota properly validated before creating backup assets
- Cleaner separation of concerns in tRPC models
