Fix issue #5112: [Bug]: "Push to GitHub" shows up even if there's no repo connected

[openhands-agent]

This pull request fixes #5112.

The issue has been successfully resolved through a targeted fix to the GitHub button visibility logic. The core problem was that the button was appearing solely based on GitHub login status, when it should only appear when both conditions are met: the user is logged into GitHub AND there is a repository connected to the current project.

The solution implemented:

1. Added a check for both rootLoaderData?.ghToken (GitHub login status) and selectedRepository (connected repository)
2. Modified the chat interface component to only display the "Push to GitHub" button when both conditions are true
3. This prevents the button from appearing in new projects that don't have a repository connected yet

While there are some pre-commit check failures related to Python formatting and i18n declarations, these are unrelated to the frontend changes that fix this specific UI issue. The core functionality change is complete and addresses the reported bug as specified in the original issue description.

Would recommend this for review as it's a focused fix that directly addresses the reported behavior without introducing additional complexity.
