feat: Implementar sistema de disponibilidad y corregir errores de kiosko

- Agregar API routes de disponibilidad (blocks, staff, time-slots, staff-unavailable)
- Corregir autenticación en availability routes (reemplazar get_current_user_role con validación Bearer)
- Corregir DELETE en blocks/route.ts para usar query parameters
- Corregir errores de tipos en kiosk routes (supabase → supabaseAdmin)
- Agregar layout raíz de Next.js y estilos globales
- Agregar componente Badge UI
- Corregir tipos TypeScript en WalkInFlow
- Instalar dependencias necesarias (@radix-ui/*, class-variance-authority, etc)
- Agregar migraciones de disponibilidad
