Refactor configuration access to use latest_arc() instead of latest_ref()

- Updated multiple instances in the codebase to replace calls to latest_ref() with latest_arc() for improved performance and memory management.
- This change affects various modules including validate, enhance, feat (backup, clash, config, profile, proxy, window), utils (draft, i18n, init, network, resolve, server).
- Ensured that all references to configuration data are now using the new arc-based approach to enhance concurrency and reduce cloning overhead.

refactor: update imports to explicitly include ClashInfo and Config in command files
