fix(quiz): persist on-demand poll records

[cursor]

📝 Description

What:

• Persist /genquiz on-demand quiz poll metadata after Telegram successfully returns a poll id.
• Store on-demand quiz records under a poll-specific sort key to avoid overwriting the daily quiz row.
• Add regression coverage for the on-demand quiz success path.

Why:

• Without a saved quiz record, bot poll_answer handling cannot resolve the poll id and silently ignores answers, causing score/streak data loss for on-demand quizzes.

Verification:

• python3 -m pytest tests/test_quiz_service.py tests/test_webhook_poll_answer.py tests/test_quiz_streak.py
• python3 -m pytest
