Reviewer's Guide by Sourcery

The pull request refactors the Search component to support a generic type parameter and an async OnSearch callback, allowing for more flexible and dynamic search operations. It also updates related unit tests and sample components to align with these changes. Additionally, the AutoFill component's Template parameter is deprecated in favor of ItemTemplate, and the OnSearch method in the Coms component is adjusted to handle nullable strings.
