feat: enhance application structure and improve accessibility

- Refactor various components for better readability and maintainability.
- Update HTML templates to include `alt` attributes for images and `for` attributes for labels.
- Implement reactive forms in OTP component and improve token management in AuthService.
- Adjust routing to redirect to 'admin/about' by default.
- Remove deprecated interceptor implementation and streamline authentication logic.
- Add console logs for better debugging during initialization.
