v4.0.0 - React 19 Upgrade

What's Changed

Upgraded to React 19.1.0: Migrated the entire project to react@^19.1.0 and react-dom@^19.1.0
Comprehensive Dependency Update: Updated numerous packages, including framer-motion, and resolved complex dependency conflicts
Modernized SCSS: Replaced deprecated Sass functions (map-merge, nth) with their modern module-based equivalents (map.merge, list.nth)
Webpack 5 Polyfills: Integrated necessary polyfills (crypto-browserify, stream-browserify, etc.) for Node.js core modules no longer included in modern webpack
Build Configuration: Implemented a robust config-overrides.js to manage webpack fallbacks and suppress excessive console warnings from third-party libraries
Bootstrap 5 Compatibility: Updated all components and classes to be fully compatible with Bootstrap 5 (e.g., text-bg-* badges, me/ms spacing)

Fixed Collapsed Sidebar Alignment: Resolved persistent icon alignment issues in the collapsed sidebar for both static and hover states, ensuring pixel-perfect centering
Fixed User Profile Dropdown: Corrected the positioning of the user profile dropdown to prevent it from rendering off-screen on larger viewports
Fixed reactstrap Components: Refactored Form and FormGroup components to remove the deprecated inline prop, aligning them with React 19 and Bootstrap 5 standards
Fixed Vector Maps Component: Resolved a critical data fetching error by replacing a dead URL with a local data source

This is a major version update. While we've maintained full feature parity, please review the upgrade guide if you're extending this theme.
