chore(config): add initial project configuration and setup files

- Add .env.example with Microsoft Azure AD and Google Cloud OAuth client ID placeholders
- Create .gitignore to exclude node_modules, build output, env files, IDE, OS, logs, and test coverage
- Add .prettierrc for consistent code formatting rules
- Add README.md with project overview, features, setup instructions, project structure, and technologies used
- Add components.json with UI framework and alias configuration
- Configure eslint.config.js for linting TypeScript and React code with recommended settings
- Add index.html as application entry point with root div and main script reference
- Add package-lock.json capturing full dependency tree and versions for reproducible installs
