Add a 'Question Timer' toggle to game settings that lets the host disable
the countdown timer. When disabled, questions show ∞ instead of a countdown,
the host gets an 'End Question' button to manually advance, and all correct
answers receive maximum points.
Also fix a bug where per-question time limits were ignored — the timer and
scoring always used the hardcoded 20-second default instead of each question's
individual timeLimit.
- Host can kick players from lobby (removes from game, clears presenter if needed)
- Client can voluntarily leave game
- Fix browser-compatible base64 decoding for document upload (atob vs Buffer)
Add a centralized game configuration system that allows customizable
scoring mechanics and game rules. Users can now set default game
configurations that persist across sessions, and individual quizzes
can have their own configuration overrides.
