Replace the complex JSON-based backup system (~2000 lines) with a simple
approach that copies the SQLite database and all data directories into a
single ZIP file.
Backend changes:
- Add close_all_connections() and reinitialize_database() helpers to database.py
- New GET /backup endpoint: creates complete ZIP with bambuddy.db and all
data directories (archive, virtual_printer, plate_calibration, icons, projects)
- New POST /restore endpoint: extracts ZIP, replaces database and directories,
requires restart after restore
- Move legacy endpoints to /backup-legacy and /restore-legacy for transition
Frontend changes:
- Simplify api.exportBackup() - no longer takes category parameters
- Simplify api.importBackup() - no longer takes overwrite parameter
- Remove BackupModal and RestoreModal components from GitHubBackupSettings
- Add simple Download/Restore buttons with inline logic
- Add blocking modal overlay during backup/restore operations
- Add beforeunload handler to prevent accidental navigation
- Show operation status messages during backup/restore
Benefits:
- ~100 lines vs ~2000 lines of backup/restore code
- Complete by definition - SQLite database contains ALL data
- No code changes needed when schema changes
- No ID remapping required - IDs stay the same
- Faster - file copy vs querying all tables
Resolved conflicts:
- CHANGELOG.md: Kept both HA Script Support and STL Thumbnail features
- database.py: Kept both migration sets (UNIQUE constraint removal + queue columns)
- SmartPlugCard.tsx: Merged script UI support with base styling
- static/: Rebuilt frontend with merged changes

Docker Integration Test Fix
The /api/v1/settings endpoint was returning 404 because:
1. The route was defined at /settings/ (with trailing slash)
2. Curl without -L doesn't follow redirects
3. The catch-all route was intercepting API paths
Fixes:
- Added routes for both with and without trailing slash in settings.py and notification_templates.py
- Updated catch-all in main.py to raise proper HTTPException for API routes
