fix: properly focus password input on error without using $el or ref

- Removed `passwordInput` ref and reliance on `$el` to access the input field inside the `Input` component.
- Fixed `TypeError` caused by calling `focus()` on the component instance.
- Now focusing the password input via `formElement.password` in the form's submit error handler.
- Used `nextTick` to ensure the DOM is updated before focusing.
- This approach is cleaner, avoids reliance on component internals, and works reliably with shadcn-vue components.
