Slice 5 (final) of observability-service-registry. Completes the move to service-registry-only observability config: no observability service env vars remain. - config.py: removed alertmanager_url + alertmanager_webhook_url fields. - docker-compose.yml / docker-compose.dev.yml: removed ALERTMANAGER_URL, ALERTMANAGER_WEBHOOK_URL (backend env), and VITE_GRAFANA_URL, VITE_PROMETHEUS_URL (frontend build args / dev env). - frontend/Dockerfile: removed the VITE_GRAFANA_URL / VITE_PROMETHEUS_URL ARG, build-stage ENV, and dev-stage ENV lines. - docs: REQUIREMENTS decision-log entry; CHANGELOG Added/Changed/BREAKING for the observability service registry; backend/README monitoring section (Observability page, services page config, http_sd_configs, new health endpoints, log-only webhook). The only observability env var remaining is PROMETHEUS_ENABLED (Manage's own /metrics toggle). Grep-gated: no live references to the removed vars/fields in backend src, frontend src, compose, or Dockerfile. ruff clean; 239 backend tests pass; frontend 0 lint errors, build clean, 72 tests pass. .env.example is assistant-edit-blocked; user follow-up noted in the SDD tasks: drop the removed vars there too.
