Refactor database node configuration to unify database operations

- Consolidated individual database operation types (query, insert, update, delete) into a single "database" entry for improved clarity and maintainability.
- Updated connection suggestions and common patterns to reflect the new unified structure, enhancing the overall configuration of database nodes.
