fix: resolve linting issues and add dropdown tabindex

Fixed ESLint error in header component:
- Added tabindex="-1" to dropdown menu for keyboard accessibility
- Ensures dropdown is focusable for screen readers

Auto-fixed formatting issues:
- Ran ESLint --fix to auto-correct stylistic issues
- Fixed key spacing in achievement constants
- Fixed object key ordering

Test Results:
- ✅ All 123 tests passing (1 API + 122 shared-types)
- ✅ Frontend linting passes
- ✅ Only non-critical warnings remain in e2e and shared-types
