feat(cloud): support China region for token-based login
The /cloud/token endpoint always used the global Bambu API endpoint,
so users with China-region access tokens could not validate their
token. The password login flow already exposes a region selector; this
brings the token flow to parity.
GitHub backup can now optionally include spool inventory (with usage
history) and print archive metadata as JSON. Both toggles are off by
default. No binary files (gcode/3MF) are included.
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
