Complete auto-startup installation system for Raspberry Pi Zero

- Enhanced install_minimal_xorg.sh with full automatic startup configuration
- Added systemd service for robust signage player auto-start
- Configured autologin and X server auto-launch on boot
- Added multiple startup methods (systemd, bashrc, rc.local) for reliability
- Disabled screen blanking and power management for kiosk operation
- Updated requirements.txt with proper version specifications
- Fixed run_tkinter_debug.sh for correct directory structure
- Added comprehensive logging and error handling
- Optimized for headless Raspberry Pi Zero deployment

Features:
✅ Plug-and-play operation - boots directly to signage player
✅ Automatic restart on crashes
✅ Multiple fallback startup methods
✅ Complete dependency installation
✅ Service management commands
✅ Hardware optimizations for digital signage
