MD5 in bambu_mqtt.py is used for AMS tray change detection fingerprinting,
and SHA1 in github_backup.py matches Git's blob hash format. Neither is
used for security purposes, so mark them explicitly to satisfy Bandit B303
and CodeQL py/weak-cryptographic-algorithm findings.

- Remove created_at from backup_metadata.json
- Remove exported_at from K-profile files
- Remove exported_at from cloud profile files (filament, printer, process)
- Remove exported_at from app settings backup
- Git already tracks file modification history, so these were redundant
- Backups now only show changes in git diff when actual data changes
The scheduler compared timezone-aware datetime.now(UTC) with naive
datetimes from the SQLite database, causing "can't compare offset-naive
and offset-aware datetimes" error.
Fixed by adding UTC timezone to naive datetimes before comparison.
New feature to automatically backup K-profiles, cloud profiles, and app
settings to a GitHub repository with scheduled or on-demand execution.
Features:
- Configure GitHub repo URL and Personal Access Token
- Schedule backups hourly, daily, or weekly (background scheduler)
- Manual backup trigger with real-time progress tracking
- Skip unchanged commits (only creates commit when data changes)
- Backup history log with status and commit links
- Requires Bambu Cloud login for full profile access
- New Settings → Backup & Restore tab consolidating all backup options
- GitHub backup config included in local backup/restore (except PAT)
Backend:
- New models: GitHubBackupConfig, GitHubBackupLog
- New service: GitHubBackupService with scheduler and GitHub API client
- New routes: /github-backup/* for config, status, logs, and triggers
- Updated settings.py to include github_backup in backup/restore
Frontend:
- New GitHubBackupSettings.tsx component with auto-save
- Updated SettingsPage with Backup tab and status indicator
- Added API types and methods to client.ts
Tests:
- Backend integration tests for all GitHub backup API endpoints
- Frontend API type and endpoint tests
