- Increase market_api polling cadence from 60s to 900s (15 min).
The prev-day bar endpoint returns the same data all day, so polling
every minute wastes API quota. 50 tickers at 15-min cadence = ~3.3
req/min, well within the 5/min rate limit.
- Reduce market_api rate limit from 30/min to 5/min to match.
- Fix backtest replay to query market_snapshots with data->>'c' for
close prices instead of nonexistent market_data.close_price column.
- Enrich backtest recommendations with prices from market_snapshots
and sectors from companies table.
