Retention and per-field value capping already ran automatically every poll
cycle, but the dashboard showed only a single "DB size" line — no
visibility into what got deleted, which fields are hitting the
max-values-per-field cap, or whether disk space is reclaimable, without
SSHing in. baseline.py's maintenance() now also reports the specific
(stream, entity, field) rows it trimmed for exceeding the cap, surfaced in
a new Baseline Maintenance dashboard panel alongside size/reclaimable bytes
and rows deleted last cycle. Deliberately no live-vacuum button: VACUUM
needs the service stopped first, so the dashboard only shows when it's
worth doing and points at the existing offline CLI command.

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.

Completes the last deferred item from ROADMAP §0: entities recognized as
the same real-world concept across enabled streams (e.g. srcip in both a
firewall and an IIS stream) now share baseline knowledge of entity
presence/age and known relationship-target values, instead of each stream
learning it cold. Implemented additively (synthetic shared_entity:<group>
namespace in the existing baseline.py tables, no schema migration), scoped
to entity presence + relationship known-values only — per-stream
distribution baselines stay untouched. Also fixes a latent alias-map
collision bug found while building this (ALIAS_CANONICAL_BY_FIELD let
"context" silently steal "hostname"/"dns_query" from their own canonical
groups).
