🧪 No relevant tests

🔒 Security concerns

Sensitive information exposure:
The new import/export functionality in `pkg/api/server.go` and `cmd/api_client/api_client.go` could potentially expose sensitive information if not properly secured. The code should be carefully reviewed to ensure that only authorized users can import/export data and that the exported data does not contain any unintended sensitive information.

⚡ Key issues to review

Data Model Changes
Significant changes to data models (Content, ContentRule, Application) including new fields and YAML serialization. This needs careful review to ensure data integrity and backwards compatibility. Import/Export Logic
New import and export functionality for apps, rules, and contents. This needs thorough review to ensure data consistency and security during import/export operations. New CLI Functionality
Added functionality for importing apps from files or directories. This needs review for proper error handling and security considerations when processing external files.
