refactor: reorganize project structure and improve code quality

- Move CI/CD configs to config/ci/ directory
- Reorganize scripts into categorized directories (deployment, monitoring, testing, utils)
- Consolidate documentation into docs/ directory with proper structure
- Update linting and testing configurations
- Remove obsolete test reports and performance summaries
- Add new documentation for code quality tools and contact form security
- Improve project organization and maintainability
- Fix lint-staged config to only lint JS/TS files
- Disable react/react-in-jsx-scope rule for Next.js compatibility
- Ignore scripts and test config directories in ESLint
