Add ProfileApi for profile CRUD operations via HttpClient

Introduced ProfileApi class in ReC.Client.Api to handle profile-related API endpoints. Supports retrieving, creating, updating, and deleting profiles using an injected HttpClient. Methods accept cancellation tokens and utilize helper methods for query building and JSON serialization. Includes XML documentation for all methods and parameters.
