feat: enhance property setter migration with smart update logic

[iamtalib13]

Overview
This PR improves the robustness of the create_property_setter utility script to ensure efficient and accurate synchronization of property setters.

Changes

• Infrastructure: Refactored propms/utils/create_property_setter.py to implement a Smart Update mechanism.
• Composite Key Check: Replaced simple name-based skipping with a composite key validation (doc_type, field_name, property).
• Value Normalization: Added logic to compare existing database values with JSON values, ensuring updates only trigger when an actual change is detected.
• Optimization: Prevents redundant database writes and ensures all JSON-defined setters are correctly applied during bench migrate.

Impact

• Faster and more reliable migrations.
• Ensures property setter changes in JSON files are always in sync with the database.

Testing

• Verified via bench migrate: Confirmed that existing setters are skipped and only modified values are updated.
