Fix WPF single-file deployment crash and improve installer

- Disable single-file publishing (causes DirectWrite/font crash in WPF)
- Switch to multi-file self-contained deployment
- Update WiX installer to harvest all publish files using heat.exe
- Fix tray icon loading issue by including all necessary DLLs
- Reduce MSI size while maintaining all functionality

Fixes:
- System.TypeInitializationException crash on startup
- Missing tray icon (now shows DT logo correctly)
