fix(orchestrator): keep polling while text stays selected

The hub page skipped every 10 s state poll while any text was selected, so operator rows that operator.py run had closed stayed on screen until the selection ended (2026-11-12: no /api/state from 09:29 to 09:54 while the CLI closed 19 rows). A selection now holds the poll back for at most 20 s, and returning to the window reloads at once.

🎯 Fix: 90 %
💥 Break: 3 %
💸 Cost: 100 %
⏱️ Time: 100 %
🛡️ Security: 100 %
🏆 Score: 87
🚦 Gate: ✅ 90/5, cost and time <= 100, security 100 %
