status code mappings for common error categories.

errors (like Unknown Column) and return a 400 Bad Request instead of
a generic 500 Internal Server Error.

Added badge_type_code, badge_type_code_override, member_type_code, member_status, and registration_type_code to the searchable_fields list for event_badge.
Updated Journal_Base and Journal_Entry_Base to explicitly remove integer IDs (journal_id, journal_entry_id) during validation to prevent mixed-type ID collisions. This ensures the Journal module adheres to the highest V3 Vision standard compliance.
Updated Post_Base and Post_Comment_Base to ensure integer IDs (post_id, post_comment_id) are explicitly removed during validation to prevent mixed-type ID collisions. This hardens the V3 Vision standard compliance.
Updated Contact_Base and User_Base (including New/Out variants) to use standardized string IDs mapped from random IDs via root_validator. Removed legacy integer ID fields and lookup validators to support V3 Vision standards. This completes the refactor chain for Person and Post dependencies.
Updated Event_Presentation_Base, Event_Location_Base, and Event_Abstract_Base (and Base_New/In) to use standardized string IDs mapped from random IDs via root_validator. Removed legacy integer ID fields and validators to ensure API responses comply with the V3 Vision standard.
