Rename grafana-prometheus-polish -> observability-service-registry and
rewrite proposal/design/tasks for the approved vision: all observability
integration (alertmanager, grafana, prometheus) configured as service-
registry instances in the UI, surfaced on a dedicated page, with widgets
per service definition -- nothing in the env.
Key scope decisions captured:
- Add alertmanager as a 6th service type + active_alerts widget.
- Rewire /alerts + /alertmanager-status to resolve from service records
(first-enabled-instance default; no primary flag in v1).
- Add /grafana-status + /prometheus-status health endpoints.
- Observability page discovers services; kill VITE_GRAFANA_URL /
VITE_PROMETHEUS_URL deep-links.
- Webhook receiver stays log-only (drop the outbound forward).
- Remove PROMETHEUS_FILE_SD_DIR + the file-writer; external Prometheus
uses http_sd_configs against GET /api/monitoring/prometheus-targets.
build_node_exporter_targets + that endpoint stay.
- PROMETHEUS_ENABLED stays (Manage's own /metrics toggle).
- End state: zero observability *service* env vars.
