Refactor repository pattern and mark methods obsolete

Updated `IRepository<TEntity>` to introduce new reading methods and mark existing ones as obsolete. The `CRUDRepository` class is now deprecated, encouraging a transition to alternative implementations. Significant changes in `DbRepository<TDbContext, TEntity>` include the removal of old read methods in favor of a new `Read` method returning `IReadQuery<TEntity>`. Added a `ReadQuery<TEntity>` class to enhance querying capabilities with a fluent API. Obsolete methods are organized under a `#region Obsolete` directive for better management.
