Editors can now control the order applications appear in, the same way they
already reorder Hero slides.
- Application gains an `order Int @default(0)` column (additive migration
20260605120000_add_application_order, IF NOT EXISTS, safe for deploy) plus
an (isActive, order) index.
- New reorderApplications(orderedSlugs) server action — single $transaction
renumbering, mirrors reorderHeroSlides.
- HQ applications panel: rows are now draggable by a grip handle (HTML5 DnD,
optimistic local reorder, persisted on drop, toast feedback).
- All public-facing queries now order by [order asc, createdAt asc]: home
ApplicationsDashboard + GlobalOperations, the footer apps list, and the
HQ list itself. Existing rows default to 0 so current order is preserved
until the editor drags something.
Verified: production build compiles, TypeScript clean.
