- Introduced `CRUDBaseAsync` for reusable async operations. - Configured async database connection using SQLAlchemy 2.0 patterns with `asyncpg`. - Added `deleted_at` column and soft delete functionality to the `User` model, including related Alembic migration. - Optimized queries by adding composite indexes for common user filtering scenarios. - Extended tests: added cases for token-based security utilities and user management endpoints.
