refactor(preferences): streamline API configuration retrieval

- Updated ApiServerService and ClaudeCodeService to use the new `getMultiple` method for fetching API server configuration from the preference service.
- Simplified the structure of the returned configuration object, enhancing readability and maintainability.
- Removed deprecated raw preference retrieval methods in favor of the new mapping approach.
