Add DeleteRecActionsCommand and handler for deletion

Introduced `DeleteRecActionsCommand` and its handler to enable
deletion of `RecAction` entities based on `ProfileId`. Added
necessary `using` directives and organized the code under the
`ReC.Application.RecActions.Commands` namespace. The handler
uses dependency injection for the repository and performs
asynchronous deletion with cancellation support.
