+    This abstract base class provides common functionality for creating entities

+    - entity_type_name: Human-readable name for logging (e.g., 'Park')
+    - required_fields: List of required field names (e.g., ['name', 'park_type'])
+    
+    Features:
+    - Moderator bypass: Auto-approves for users with moderator role
+    - Atomic transactions: All-or-nothing database operations
+    - Comprehensive logging: Full audit trail
+    - Submission items: Each field tracked separately for selective approval
+    - Placeholder entities: Created immediately for ContentSubmission reference
