Fix quotetable heading, stale click state, and parallel fetch

- Rename "Positions" → "Quotes" (heading was misleading; implies holdings)
- Always clear _qt_click on read so stale values from removed tickers
  don't persist across rerenders
- Replace serial get_latest_price + get_company_info calls with
  parallel ThreadPoolExecutor fetch of get_company_info only;
  regularMarketPrice/currentPrice from info is sufficient for the table
  and halves the number of yfinance calls
