feat(health): surface pending-updates counts on the Health dashboard and CLI (ScadaBridge#63)
Health page gains PendingUpdatesHealthTiles (stale instances / sites with stale artifacts, Deployer+Administrator only, site-scope narrowed, shared cache). New GetPendingUpdates management command (Deployer) and 'health pending-updates' CLI leaf. Flatten/cache computation untouched; the command reads IPendingUpdatesEvaluator directly because the UI cache is not reachable from ManagementService.

@* Gitea #63: pending-updates KPI tiles on the Health dashboard. Two counts read from the
|

same process-wide IPendingUpdatesCache the rail indicator and Sites page use, so this
|
||||
costs no extra fleet flatten. Visible only to Deployer/Administrator (the roles that can
|
||||
act on it, same gate as the rail indicator) and narrowed to a site-scoped operator's
|
||||
permitted sites. A read failure is shown as unavailable, never as a clean "0". *@
