feat: Enhance Kol Generation Service with web search and knowledge group support

- Added `EnableWebSearch` and `KnowledgeGroupIDs` fields to `KolGenerationSubmitRequest`.
- Updated `Submit` method in `KolGenerationService` to handle new request fields.
- Integrated web search and knowledge group validation based on card configuration.
- Introduced caching mechanisms in `KolPackageService`, `KolPromptService`, and `KolSubscriptionAdminService` to improve performance.
- Implemented knowledge context resolution in `KolGenerationWorker` to enrich prompts with relevant knowledge snippets.
- Added utility functions for handling card configuration in both backend and frontend.
- Created tests for knowledge extraction and rendering to ensure accuracy and reliability.
