Apply react_on_rails:install generator updates

Ran the react_on_rails:install generator to get latest v16.1.1 improvements: - Enhanced bin/dev script with better development server management - Added Procfile variations for different development modes: - Procfile.dev: HMR mode with webpack-dev-server - Procfile.dev-static-assets: Watch mode without HMR - Procfile.dev-prod-assets: Development with production assets - Updated webpack configurations for v16.1.1 compatibility - Updated shakapacker.yml configuration - Updated babel.config.js - Updated react_on_rails initializer - Added generateWebpackConfigs.js helper These updates provide better development experience and align with React on Rails v16.1.1 best practices. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
