fix(torghut): advance past stale feature batches

[gregkonush]

Summary

• Advance the trading signal cursor after staleness-only feature-quality failures without evaluating decisions or submitting orders.
• Keep non-staleness feature-quality failures fail-closed, including schema mismatches, duplicates, and non-monotonic batches.
• Bump Torghut TA and paper TA restart nonces so both jobs load the deployed TA_QUOTE_STALE_AFTER_MS=15000 ConfigMap values.
