fix: remove as-any casts, type Dashboard data properly

- Route handlers: add exhaustive return after error checks so TypeScript
  narrows the union and result properties are accessible without casts
- attendance.service: use Prisma.attendanceGetPayload for included relations
- projects.service: remove unnecessary cast on orders relation
- Dashboard.tsx: replace Record<string,any> with proper DashData interface
