Frontend now drives Impressions / CTR / Spend from real per-variant
metrics (cycle_metric) rather than hardcoded zeros + fake +12% / -0.3%
deltas. Adds state.data.metricsByCycle keyed by cycle id; populated
via _fetchCycleMetrics which hits the panel-update endpoint directly
(no CMO chat dispatch needed — the route calls gRPC live per request).
After every cycles load (refresh-cycles or list-cycles ingest), fans
out one metrics fetch per cycle. _deriveKpis flattens all metrics
arrays, sums impressions/clicks/spend, computes real CTR from
clicks/impressions. Spend bar now reflects $spend / $budget_total
from real values instead of falling back to the $6,000 default floor.
Plugin route _real_payload_for gains a new branch:
adwright_get_cycle_metrics?cycle_id=N → core.get_cycle_metrics_tool(N).
Fake deltas dropped — real deltas need a previous-window snapshot
the backend doesn't supply yet.
Verified live: metricsByCycle.1 populated with backend's [{variant_id:1,
impressions:0, ...}] record. All metric values still zero in this
sandbox because no ads have dispatched.
