Redesign admin dashboard: pipeline view, round-specific stats, smart actions

Complete rewrite of the admin dashboard replacing the 1056-line monolith with
modular components. Key improvements:

- Competition pipeline: horizontal visualization of all rounds in pipeline order
  (by sortOrder, not creation date) with type-specific icons and metrics
- Round-specific stats: stat cards dynamically change based on active round type
  (INTAKE shows submissions/docs, FILTERING shows pass/fail/flagged, EVALUATION
  shows assignments/completion, fallback shows generic project/jury stats)
- Smart actions: context-aware "Action Required" panel that only flags the next
  draft round (not all), only flags unassigned projects for EVALUATION rounds,
  includes deadline warnings with severity levels (critical/warning/info)
- Active round panel: detailed view with project state bar, type-specific content,
  and deadline countdown
- Extracted components: project list, activity feed, category breakdown, skeleton

Backend enriched with 17 parallel queries building rich PipelineRound data
including per-round project states, eval stats, filtering stats, live session
status, and deliberation counts.
