k8s-upgrade: nightly Slack report monitor + scope chain-failed alert to phases
Adds a daily visibility layer so every night's autonomous-upgrade outcome is
reviewable at a glance during the upgrade-cleanup window (Viktor: "track every
night's upgrade for the next 7 days; clean up all bugs and blockers").

Last night (2026-06-20) confirmed BOTH prior fixes work in production: the
detector resolved target 1.35.6 (k8s_upgrade_available) and the compat gate
correctly REFUSED it (k8s_upgrade_blocked=1 -> K8sUpgradeBlocked) because ESO
v0.12 (<=1.31) and kyverno v1.16 (<=1.34) don't support 1.35.

What's here:
- CronJob k8s-upgrade-nightly-report (06:07 UTC) -> one Slack summary/morning:
  running version, detector freshness, detected target, outcome (no-op /
  blocked+live reasons / upgraded / in-progress / detector-stale), recent jobs.
  Read-only: reads Pushgateway gauges + live nodes/jobs, re-runs compat-gate.py
  for fresh blockers; reuses the chain SA + slack_webhook + scripts ConfigMap.
  Pure helpers unit-tested (test_nightly_report.py, 8 cases incl. a real
  v-prefix bug TDD caught). Verified end-to-end in-cluster (posted to Slack).
- K8sUpgradeChainJobFailed regex scoped from `k8s-upgrade-.*` to
  `k8s-upgrade-(preflight|master|worker|postflight)-.*` so the new report job
  (or any future helper) can't false-trip the chain-wedged alarm.

Manual state repair (no git artifact): imported the orphaned `alert-digest`
CronJob into the monitoring stack state
(`tg import module.monitoring.kubernetes_cron_job_v1.alert_digest monitoring/alert-digest`).
Root cause: when alert_digest was added (2026-06-12) the apply recorded its
ConfigMap + Secret but not the CronJob, so every full monitoring apply since has
failed with `cronjobs.batch "alert-digest" already exists` (Woodpecker pipeline
298 today) — surviving only via targeted prometheus applies. Now in state, so
monitoring CI applies cleanly again.
