This edition is being handled manually via email — admins need to
record what each finalist replied. Adds:
- finalist.adminConfirm — flips PENDING → CONFIRMED with attendees +
visa flags. Same cap and team-membership checks as the public flow,
audit-logged as FINALIST_ADMIN_CONFIRM.
- finalist.adminDecline — flips PENDING → DECLINED with optional
reason and triggers waitlist promotion. Audit-logged as
FINALIST_ADMIN_DECLINE.
- finalist.getConfirmationDetail — feeds the admin attendee picker.
- Per-row Confirm / Decline actions on the Logistics > Confirmations
table (PENDING rows only) backed by a shared dialog that switches
between attendee-picker and reason-input modes.

- /admin/logistics page with shadcn Tabs (3 active + 5 disabled "(soon)"
placeholder tabs for Visas / Lunch / Documents / Email Templates / Settings).
- Sidebar entry "Logistics" between Mentors and Awards (Plane icon).
- Confirmations tab: read-only table with status filter pills, browser-
local-time deadline display, attendee count, decline reason snippet.
- Hotels tab: single-hotel form (name/address/link/notes) with live
email-preview card showing what teams will see.
- Travel tab: per-attendee flight tracker with arrival/departure
datetimes, flight numbers, IATA airports, click-to-toggle status badge,
edit Sheet, and unfilled/pending/confirmed filter pills.
Smoke-tested end-to-end: navigation, sidebar entry, all three tabs
render, hotel save persists to DB and renders in preview card.
