Pull Request Overview

This PR fixes issues with generating sharding DAO configurations when working with multiple sharding pattern tables. The fix ensures that sharding handlers are properly named and configured with the correct table prefixes for different sharding patterns.

• Fixes hardcoded generic sharding handler name to be table-specific
• Adds proper sharding prefix template variable configuration
• Extends pbentity generation to support sharding patterns
• Updates test cases to cover multiple sharding table scenarios
