monitoring: consolidate all Slack alerting to #alerts, abandon #security
Some checks are pending
ci/woodpecker/push/default Pipeline is running
Details

Browse source 
The dedicated #security Slack channel was unreachable: the shared incoming
webhook (Vault secret/viktor -> alertmanager_slack_api_url) belongs to a
Slack app that isn't a member of #security, so any channel override on it
returns HTTP 404 channel_not_found. The goldmane-edges-digest was silently
failing for that reason.

Per request ("dump the security channel, post in an existing one"), route
everything to #alerts instead:
- alertmanager slack-security receiver -> #alerts (keeps its [SECURITY/<sev>]
  title styling so security-lane alerts still stand out in the shared channel)
- goldmane-edges-digest CronJob SLACK_CHANNEL -> #alerts (comment only; value
  was already switched and applied last change)
- AggregatorDown / DigestFailing alert summaries reworded to say #alerts
- docs swept (security.md, monitoring.md, ADR-0014, goldmane runbook,
  .claude/CLAUDE.md, service-catalog, CONTEXT.md) to drop the
  "invite the app / flip back to #security" caveats and state the
  #security abandonment + #alerts consolidation as the current routing.

Monitoring stack applied (alertmanager rolled, live config verified:
slack-security channel is now #alerts).
