Updated `ReC.API.csproj` to include `Swashbuckle.AspNetCore` (v6.6.2) for Swagger/OpenAPI documentation. Removed an unused `<ItemGroup>` referencing the `Controllers\` folder.
Added a new `ActionController` with a `[Route("api/[controller]")]` and `[ApiController]` attributes. Introduced a `Trigger` HTTP POST endpoint that accepts a `profileId` parameter. The method is currently unimplemented and throws a `NotImplementedException`.
