Add GET /api/dashboard/summary aggregating pipeline status, category
distribution, publish summary, and outperformers in one call. Rewrite
dashboard.html with 5 KPI cards, pipeline funnel, publish status, and
category/source-format breakdowns (CSS bars, no chart lib).
Backend: ChannelVideoRepository counts (shorts/uncategorized),
PublishPackageRepository.countByStatus, pipelineStats shorts/longForm,
CategoryService.distribution, PublishService.dashboardSummary, new
DashboardService + DashboardApiController.
Fix: PublishService.list(null) hit UnsupportedOperationException because
findAll(Sort) uses Criteria, which rejects nullsLast precedence. Route the
no-status path through a @Query method so Sort is appended as HQL ORDER BY
(supports NULLS LAST). Also fixes the latent bug in /api/v1/publish all-list.
