Refactor project idea generation and clean up code

Cleaned up `using` directives and adjusted `namespace` declaration in `GenerateProject.cs` for better readability. Refactored CosmosDB query logic to use embeddings generated from `certificationCode` and `skillName`, and updated the loop to concatenate service names into `projectServices`. Modified `_contentGenerationService.GenerateProjectIdeaAsync` to use `projectServices` and `skillName`. Updated `GenerateProjectIdeaAsync` method in `ContentGenerationService.cs` to reflect new parameters and prompt structure. Ensured response format remains valid JSON.
