Add ticker symbol voting (e.g. QPL3++, TMP2--)

Extend vote detection to recognize game ticker symbols alongside the
existing thisgame++/-- syntax. Each symbol maps to a specific game so
users can vote for any game by its stock-style ticker. The matched
ticker is sent to the API via a new optional `ticker` field in the
vote request.
