Fix ffpyplayer offline wheel and update install scripts

- Rebuilt evdev wheel for cp313 aarch64 (was missing from repo)
- Updated install.sh: add --system-site-packages to venv, verify imports
- Updated start.sh: activate .venv before running player
- Updated run_player.sh: activate .venv before running player
- Added pip fallback for kivy/ffpyplayer if apt/pip install misses them
