1. Approve Adoption

• Endpoint: PATCH /adoption/:id/approve
• Only accessible by ADMIN
• Validates adoption is PENDING
• Updates status → APPROVED

2. Reject Adoption

• Endpoint: PATCH /adoption/:id/reject
• Only accessible by ADMIN
• Validates adoption is PENDING
• Updates status → REJECTED
• Accepts optional rejection reason
• Uses Prisma transaction for safety

---

🔒 Validation & Authorization

• ADMIN role required (JwtAuthGuard + RolesGuard)
• Prevents invalid transitions (non-PENDING)
• Returns:
  • 404 if not found
  • 400 if invalid state
  • 403 if unauthorized

⚠️ Notes

• No schema changes were made (as required)
• approvedAt and pet status updates were not implemented due to schema limitations

• Rejection flow tested (with/without reason)
• Authorization checks verified
