feat(observability): scale-to-zero alert + tile + catalog (#54)#55

…#54) Rule 25 artifacts for instant_deploy_scaled_to_zero_total{outcome} + instant_deploy_idle_apps (emitted by worker/internal/jobs/deploy_idle_scaler.go). - Prom rules (instant-worker-deploy-scale-to-zero group): DeployScaleToZeroWakeFailed (wake_failed > 0 / 15m → P1: app stuck asleep), DeployScaleToZeroScaleDownFailures (scale_failed >= 5 / 30m → P2: savings not landing, no customer impact). - NR alert: deploy-scale-to-zero-fail.json (wake_failed → CRITICAL). - Dashboard: two tiles on instanode-reliability.json — asleep-apps billboard + scale-outcome stacked-bar. - METRICS-CATALOG.md: rows for the counter (lazy, 4 outcomes primed) + the gauge (eager). All INERT until an operator sets DEPLOY_SCALE_TO_ZERO_ENABLED — the series stay 0 and the alerts stay quiet until the feature is canaried on.

…tile + catalog (Task #55) (#56) Wires monitoring for instant_resource_count_limit_blocked_total{service,team_tier} (api), the metric emitted when the per-service resource-COUNT cap rejects a provision with 402. Closes the rule-25 gap for Task #55's metric: - newrelic/alerts/resource-count-limit-blocked.json — P2 (abuse/observability), WARN on > 20 blocks/h per service+tier (derivative over 1h). - k8s/prometheus-rules.yaml — ResourceCountCapBlocked rule (instant-api group). - newrelic/dashboards/instanode-reliability.json — stacked-bar tile by service+tier. - observability/METRICS-CATALOG.md — catalog row (lazy CounterVec; INERT until RESOURCE_COUNT_CAPS_ENABLED). All artifacts are inert until the operator enables the api flag — the counter has zero series until the first over-cap rejection. Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
