feat: Implement DNS management for macOS

- Added `set_public_dns` and `restore_public_dns` functions in `dns.rs` to manage system DNS settings.
- Introduced `resolve` module to encapsulate DNS and scheme resolution functionalities.
- Implemented `resolve_scheme` function in `scheme.rs` to handle deep links and profile imports.
- Created UI readiness management in `ui.rs` to track and update UI loading states.
- Developed window management logic in `window.rs` to handle window creation and visibility.
- Added initial loading overlay script in `window_script.rs` for better user experience during startup.
- Updated server handling in `server.rs` to integrate new resolve functionalities.
- Refactored window creation calls in `window_manager.rs` to use the new window management logic.
