Fix Python 3.13 compatibility and installation issues

- Replaced all cp311 wheels with cp313 wheels for Python 3.13 compatibility
- Added new dependency wheels: aiohappyeyeballs, evdev, ffpyplayer
- Rebuilt install.sh with virtual environment + offline wheel installation
- Added --sudo-user/-U and --sudo-password/-W CLI arguments
- Added run_sudo() helper to avoid password prompts during installation
- Fixed 'Setting Up Player Directories' hang (cat->stdin) by using touch
- Updated start.sh to activate virtual environment before running player
- Updated run_player.sh to activate virtual environment
- Removed old cp311 incompatible wheels
- Added backup of previous install.sh as install.sh.bak
