refactor: standardize code formatting and linting configuration
- Replace .eslintrc.js with .eslintrc.cjs for better ES module compatibility - Add .prettierrc configuration for consistent code formatting - Update package.json with new lint and format scripts - Add nodemon.json for development hot reloading configuration - Standardize code formatting across all JavaScript and Vue files - Update web admin SPA with improved linting rules and formatting - Add prettier configuration to web admin SPA 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
