[bojemoi] fix(grafana,ml-threat): structured RETRAIN_ logs + dashboard aligned on log format

Commit af4788a

Description

• api.py: emit RETRAIN_METRICS, RETRAIN_CLASS {class}, RETRAIN_DIST lines after each retrain for Loki/Grafana parsing
• dashboard: update all LogQL queries to use |= “RETRAIN_*” prefix filters instead of fragile class-name + keyword combinations
• Panel 5 renamed from “Pwned Hosts” to “Malicious Test Samples” (support count from RETRAIN_CLASS malicious)
• Panel 9 log stream now shows all RETRAIN_ lines
