fix(kvb-org-queue): book a job at its own command's footprint

A command with 5+ runs is booked at its own p90 RAM and CPU share, an unlearned one at its kind's p90. The old rule took the larger of kind and command, and for an unlearned command the largest command of its kind: test-nostack-788 (docker build) sat 90 min at position 1, booked at 42.6 % RAM from a legacy gate.py hold row while test-nostack measures 5.6 %; skills make test (3.3 %) was booked at the test kind's 35 %.

🎯 Fix: 93 %
💥 Break: 5 %
💸 Cost: 99 %
⏱️ Time: 100 %
🛡️ Security: 100 %
🏆 Score: 89
🚦 Gate: ✅ 90/5, cost and time <= 100, security 100 %
