refactor(db): Move DbQueryBuilders to separate namespace

Removes obsolete query builder interface and implementations.

Introduces a new namespace for query-related classes to enhance organization.

Updates various database managers to use the new query utilities, promoting code reuse and maintainability.

Enhances query functionality, ensuring better consistency across the codebase.
