fix: Resolve ESLint configuration and fix all linting errors

- Changed npm lint script from 'next lint' to direct ESLint invocation
- Added 'lint:fix' script for auto-fixing linting errors
- Fixed 25 ESLint errors across the codebase:
  - 8 auto-fixed with --fix flag
  - 17 manual fixes (empty function warnings, type definitions)

ESLint now properly validates TypeScript and React code without
Next.js config wrapper incompatibility.

Test Results:
- ✅ npm run lint - No errors
- ✅ npm test - All tests passing
- ✅ npm run build - Clean build
