fix(frontend): handle simple question format in AskUserQuestion HITL UI

[Gkrumbach07]

Summary

• Fixes bug where the HITL (Human-in-the-Loop) user input UI never appeared when the agent called AskUserQuestion
• The component only handled structured { questions: [...] } input, but Claude Code sends a simple { question: "..." } string format — causing parseQuestions to return [] and the component to render nothing
• Adds fallback parsing for the simple format and a free-form text input when no predefined options exist

Test plan

• Trigger an AskUserQuestion tool call in a session (e.g. ask the agent something that requires clarification)
• Verify the HITL question UI renders with a text input field
• Verify submitting an answer works and the form disables after submission
• Verify the structured { questions: [...] } format still works (radio buttons, checkboxes)
• npx vitest run — all 471 tests pass
