feat: ticker symbol voting for live votes

- Add ticker column to games table with migration
- Bootstrap tickers from tickers.json config on startup
- POST /api/votes/live accepts optional ticker field for direct game
  lookup (bypasses timestamp-interval matching)
- Ticker votes work for any game, not just session games
- Update API docs and add e2e tests for ticker voting
- Version bump to 0.6.5
