Add database operation configuration to fieldConfigs

- Introduced a new 'operation' entry in fieldConfigs to define various database operations (Query, Insert, Update, Delete, Aggregate, Transaction).
- Enhanced user guidance with descriptions, help text, and examples for each operation type.
- Updated field mappings to consolidate database operation parameters under a single entry for improved clarity and maintainability.
