Refactor behaviors to Common namespace

Moved `BodyQueryBehavior` and `HeaderQueryBehavior` from
`ReC.Application.RecActions.Behaviors` to
`ReC.Application.Common.Behaviors` to reflect their broader
applicability. Updated `DependencyInjection.cs` to use the new
namespace. This reorganization improves code structure and
maintainability.
