Fix corrupted shell scripts for Docker deployment

- Fixed shebang lines (removed backslash escapes)
- Fixed negation operators (! instead of \!)
- Removed corrupted EOF markers at end of files
- Fixed ARM64 architecture support in install-ffmpeg.sh
- Ensured all scripts have proper executable permissions

These scripts are critical for Docker container initialization
and deployment verification.
