Implemented a new feature in the workflow instances' querying API, enabling filtering based on timestamps. The changes include adding a new TimestampFilter class and modifying existing classes accordingly. This new filter supports various operators such as greater than and less than, providing flexibility in filtering workflow instances.

Timestamp filtering within WorkflowInstanceList is refactored using System.Linq.Dynamic.Core for more compact expression. This change results in simpler and more efficient code, reducing repetitive code lines. The UI updates include changing the MudGrid structure to table for timestamp filters display, offering a more organized view. Also, protection against null or minimum date values during parsing and comparisons is added, increasing stability and safety of operations.

The previous Get and Post method calls for handling '/workflow-instances' have been replaced with a Verbs method for HTTP verbs and a Routes method for setting the route.

The HasIncidents property in WorkflowInstanceFilter has been updated from a bool to a nullable bool so that it can represent three states (true, false, or null) instead of only two. This allows not only to filter workflow instances that have incidents, but also those that don't have any, enhancing the flexibility of the filter in the process.

Updated search term comparison in WorkflowInstanceFilter to use "Contains" instead of "Equals" to improve search flexibility. Also, enhanced the user interface in WorkflowInstanceList by adding debounce interval for the search input for performance reasons and by adding a Close button for convenience.

The code modifies the API endpoint for WorkflowInstances. It now checks that the input provided in the request is valid before proceeding. Furthermore, a new file called 'RequiredMembers.cs' has been added, which introduces two new attributes 'RequiredMemberAttribute' and 'CompilerFeatureRequiredAttribute'.
