Introduces a new "Proxy Mode" for the Virtual Printer that enables
remote printing from anywhere in the world without VPN, port forwarding,
or Bambu Cloud dependency.
Bambuddy acts as a TLS relay between a remote slicer (Bambu Studio/
OrcaSlicer) and the local Bambu Lab printer:
Remote Slicer → Internet → Bambuddy Server → Local Network → Printer
The slicer connects to Bambuddy using the real printer's serial number
and access code. Bambuddy authenticates and relays all FTP (file transfer)
and MQTT (commands/status) traffic with end-to-end TLS encryption.
- No port forwarding required - printer stays safely on local network
- No VPN needed - connect from coffee shops, hotels, work, anywhere
- No Bambu Cloud dependency - fully self-hosted solution
- End-to-end TLS encryption on FTP (port 9990) and MQTT (port 8883)
- Works with Bambu Studio and OrcaSlicer
- Uses real printer credentials for authentication
- Automatic printer selection from connected printers
- Add SlicerProxyManager class for TLS relay (tcp_proxy.py)
- TLS termination with auto-generated certificates
- Concurrent FTP and MQTT proxy servers
- Connection lifecycle management with proper cleanup
- Extend VirtualPrinterManager with proxy mode support
- New 'proxy' mode alongside archive/review/queue modes
- Target printer selection and credential management

- Add comprehensive guide to wiki
- Add prominent feature section to website
- Backend unit tests for SlicerProxyManager
- Backend unit tests for proxy mode configuration
- Frontend tests for proxy mode UI components

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
