Fix: Fixed sql alchemy sort mixin

[miladmahmoodi]

Description

This change fixes an issue in the SqlAlchemySortMixin class where the sorting logic did not properly handle SortOrderType when it was provided as an Enum. The original code assumed sort_info.order was a string and directly compared it to SortOrderType.ASCENDING, which caused incorrect sorting behavior when an Enum was passed. The updated code extracts the value from the Enum (if applicable) and compares it against the value of SortOrderType.ASCENDING and SortOrderType.DESCENDING. Additionally, it introduces explicit error handling for invalid sort_info.order values by raising an InvalidArgumentError.

This fix ensures that sorting works correctly regardless of whether sort_info.order is passed as a string or an Enum, improving robustness and reliability of the sorting functionality.

Additional context
