- New components/admin/grand-finale/finalist-slots-card: per-category
quota editor with confirmed/pending counts, dirty-tracking, save button.
Renders an empty editor for both Startup and Business Concept categories
even when no quota exists yet.
- New components/admin/grand-finale/waitlist-card: per-category ranked
waitlist display with status badges + manual-promote AlertDialog
(audit-logged via FINALIST_MANUAL_PROMOTE).
- Round detail page: embeds both cards conditionally when
roundType === 'LIVE_FINAL'.
- New finalist router queries: listQuotas, listCategoryCounts (groupBy
on category+status), listWaitlist (rank-ordered with project relation).
Smoke-tested: setting Startup quota to 3 persists to DB; UI renders
quota editor and waitlist card cleanly with empty state.
