larssand 36516faf9a Add real detector health tooling: learning state and historical precision ...

Replaces the old Prometheus-only "detector precision" metric, which
recomputed from whatever field_deviations happened to be active in the
current poll cycle cross-referenced against live FeedbackStore rules — a
revoked or expired suppression rule made the signal vanish, and nothing was
tracked between polls. Adds DetectorPrecisionStore, a permanent append-only
log of review outcomes (kept deliberately separate from FeedbackStore's
mutable suppression rules) recorded the moment a human reviews a finding,
plus BaselineStore.detector_readiness() mirroring the existing per-field
profile_readiness() for per-detector learning state, and a plain-language
detector reference. Surfaced in a new Detector Health dashboard panel.
Observability only — nothing here changes scoring or suppression.
