merge: reconcile perf/wave1-perf with main (Wave 0 features)

Resolve conflicts from main's Wave 0 (PR #1) landing after this branch was cut:

- useViewResource.ts: main's e352aae already fixes the render loop the same way
  (load in a ref, dropped from deps) — took main's canonical version. My
  independent fix is superseded (my branch predated e352aae, which is why the
  loop reproduced live).
- JobApplicationsController.cs: keep BOTH main's IJobCvMatchService and my
  AnalyticsService (ctor gets both optional params). GetAnalyticsOverview stays
  delegated to AnalyticsService.
- Fold main's H3 additions into the extracted AnalyticsService: pipeline-driven
  funnel (JobPipeline.Normalize/Stages) + time-in-stage (StageAnalytics) and add
  StageDurationDto + TimeInStage to Models/AnalyticsDtos.cs, preserving the API
  contract the frontend expects.

Build clean; backend suite 135/135 green.
