PR 4a of the runtime service registry change.
- Remove addon pages (/addons/:addonId, AddonPage, addons/*) superseded by
service pages.
- Remove grafana_url/prometheus_url from backend config, compose, .env.example,
and README (URLs now live on service records; VITE_ frontend deep-link vars
retained).
- Add Services page (/services) with create/list/delete + sidebar nav, so
services are configurable in the tool itself and service pages are reachable.
- Update docs/REQUIREMENTS.md service-registry section; add CHANGELOG.md with
the breaking-upgrade note (MANAGE_ENCRYPTION_KEY required; grafana/prometheus
env vars removed; default widget seeding removed).
Verification: backend ruff clean, pytest 222 passed; frontend lint 0 errors,
build success, 70 tests passed.
- Refresh README feature list and remove references to the legacy
in-app monitoring charts / backend poller.
- Document configurable dashboard widgets, addon pages, and widget env vars.
- Add VITE_PROMETHEUS_URL support to frontend Dockerfile and both compose files.
- Add header comment to .env.example explaining shell-export workflow.
- Update remote server requirements to match current capabilities.
- Remove GRAFANA_URL from backend environment (backend never consumed it).
- Add VITE_GRAFANA_URL to frontend build-args (prod), dev environment, and
frontend/Dockerfile ARG/ENV so Grafana deep-links resolve correctly.
- Add ALERTMANAGER_WEBHOOK_URL to backend environment so the documented
alert-forwarding feature is reachable from compose.
- Document VITE_GRAFANA_URL in .env.example.
