Two fixes for missing intraday data:
1. Frontend: lifted selectedWindow state to page level so useTrendHistory
passes window param to the API. Previously fetched all windows with
limit=500 which exhausted the limit before reaching recent intraday
data. Now fetches only the selected window's data.
2. Scheduler: removed market-hours-only restriction from periodic
aggregation. Runs every 15 minutes 24/7 so intraday data is always
populated for backtesting regardless of market state.
