----

> [!IMPORTANT]
> Disable OAuth in iframes using `useInIframe` hook and update
`SimpleTooltip` to support conditional disabling.
> 
>   - **Behavior**:
> - Disable OAuth buttons in iframes by using `useInIframe` hook in
`oauth-button.tsx`.
> - Show tooltip "OAuth is disabled in iFrame" when OAuth buttons are
disabled.
>   - **Components**:
> - Add `useInIframe` hook in `use-in-iframe.tsx` to detect iframe
context.
> - Remove `IframePreventer` component and its usage in
`stack-handler.tsx`.
> - Update `SimpleTooltip` in `simple-tooltip.tsx` to accept `disabled`
prop to conditionally disable tooltips.
>   - **Misc**:
>     - Remove unused `useTranslation` import in `auth-page.tsx`.
>
