Fix: UploadFile button incorrectly disabled when user is logged in

[AstroMC98]

Purpose

Fix file upload button behavior in Ask page to properly restrict access based on authentication status.

Problem: The UploadFile component in Ask.tsx was using disabled={loggedIn} which incorrectly disabled the button when users were logged in and enabled it when users were not logged in - the opposite of the intended behavior.

Solution: Changed the disabled prop to disabled={!loggedIn} to match the same authentication logic used in Chat.tsx, ensuring that:

• File upload functionality is disabled when no user is logged in
• File upload functionality is enabled when a user is authenticated
• Consistent behavior across both Ask and Chat pages

Impact: This ensures proper access control for file upload features and maintains consistent user experience throughout the application.

Does this introduce a breaking change?

When developers merge from main and run the server, azd up, or azd deploy, will this produce an error?
If you're not sure, try it out on an old environment.

Code quality checklist

See CONTRIBUTING.md for more details.

• The current tests all pass (python -m pytest).
• I added tests that prove my fix is effective or that my feature works
• I ran python -m pytest --cov to verify 100% coverage of added lines
• I ran python -m mypy to check for type errors
• I either used the pre-commit hooks or ran ruff and black manually on my code.

Thank you for the PR, I'll review tomorrow in my logged-in demo environment.

Verified the fix, thanks! The e2e tests dont yet cover logged in scenarios, so we aren't able to add an end-to-end test verifying the change, but I wouldn't expect a regression for this going forward. Merging!
