fix: address trading bot issues with discover-subscribe, confirm CLOSE, and caching

- Fix /market-data/admin/discover-subscribe endpoint to fallback to module-level
  _market_data_adapter when app.state is not set (fixes adapter_unavailable issue)
- Fix /confirm endpoint to accept CLOSE action as alias for EXIT
- Fix indentation error in schema.py from_raw method
- Add tests for confirm CLOSE action, quote/price_change caching, and orphan cleanup

Fixes:
1. adapter_unavailable problem in discover-subscribe endpoint
2. /confirm accepts only ADD|HEDGE|EXIT, not CLOSE
3. quote/price_change events best_bid/best_ask caching
4. Trades EXITED through orphan cleanup (verified existing checks)
