+ *
+ * 2. ISSUE - Route param type mismatch:
+ *    - @Param('id') typed as `number` but comes as string
+ *    - No ParseIntPipe used
+ *    - Fix: Use @Param('id', ParseIntPipe)
+ *
+ * 3. SECURITY - Role-based access control implemented:
+ *    - approve/reject endpoints now use AuthGuard + RolesGuard
+ *    - Only Admin users can approve/reject validations
+ *    - FIXED: Added @UseGuards(RolesGuard) and @Roles(UserRole.Admin)
+ *
+ * 4. ISSUE - getValidationById returns null:
+ *    - Should throw NotFoundException for better REST semantics
+ *    - Fix: Add null check and throw NotFoundException
+ *
+ * 5. SUGGESTION - Add validation for id parameter:
+ *    - Consider adding validation that id is positive integer
