Simplified the `Handle` method by removing the `async` modifier
and replacing the `await` call with a direct `return` statement
for `repo.DeleteAsync`. This optimization eliminates the
overhead of creating an async state machine, as no additional
asynchronous operations or logic are performed in the method.
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.
