fix: queue short interest fetches on subscribe alongside quote/candles

- Add yfinance:shortinterest: and nasdaq:nasdaqShortinterest:
  to subscribe() initial queue list so short interest data is fetched proactively
  when a symbol is first viewed, rather than only on stale read
- FINRA remains bulk-schedule only via queue_schedules
