feat: add setup scripts (configure_env, macbook, unraid, fedora)

- configure_env.sh: interactive 50-prompt wizard with progress [N/50],
  input validation (IP, port, email, path, URL, bool, password, ssl_mode),
  conditional SSL prompts based on SSL_MODE, summary with masked passwords
- macbook.sh: Homebrew packages, envsubst, Xcode CLI tools, SSH tests
- unraid.sh: Docker verify, docker-compose + jq static binary install
- fedora.sh: Docker CE + compose plugin install, jq, docker group setup
