feat: finalization tab respects ranking overrides, grouped by category

- processRoundClose now applies reordersJson drag-reorder overrides
  when building the evaluation pass set (was ignoring admin reorders)
- Finalization tab groups proposed outcomes by category (Startup/Concept)
  with per-group pass/reject/total counts
- Added category filter dropdown alongside the existing outcome filter
- Removed legacy "Advance Top N" button and dialog from ranking page
  (replaced by the finalization workflow)
- Fix project edit status defaultValue showing empty placeholder
