fix: resolve ESLint errors and warnings

- Add emoji accessibility labels (jsx-a11y/accessible-emoji)
- Remove unused imports and variables
- Fix async functions without await
- Add dev directory to ESLint ignore list
- Add eslint-disable comment for necessary console.error
- Clean up unused route file

All ESLint errors resolved (0 errors, 33 warnings remaining)
