+-- Migration: Relax key ref format constraint
+-- Description: Allow multi-segment dot-separated key refs (e.g., "pack.prefix.name")
+-- The original constraint only allowed at most one dot: '^([^.]+\.)?[^.]+$'
+-- Sensors create refs like "python_example.counter.rule_ref" which have multiple dots.
