/**
* Unit Tests for Storage Configuration and DBAL Adapter
* Comprehensive tests for HTTP communication with DBAL backend
*
* Coverage includes:
* - Connection health checks with timeout handling
* - Snippet CRUD operations with error scenarios
* - Namespace CRUD operations
* - Data serialization (dates, objects, null values)
* - Network error handling (timeouts, connection refused, invalid JSON)
* - HTTP error responses (400, 404, 500, etc)
* - Migration operations
*/
