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.
