Refactor logging to use a centralized logging utility across the application (#5277)

- Replaced direct log calls with a new logging macro that includes a logging type for better categorization.
- Updated logging in various modules including `merge.rs`, `mod.rs`, `tun.rs`, `clash.rs`, `profile.rs`, `proxy.rs`, `window.rs`, `lightweight.rs`, `guard.rs`, `autostart.rs`, `dirs.rs`, `dns.rs`, `scheme.rs`, `server.rs`, and `window_manager.rs`.
- Introduced logging types such as `Core`, `Network`, `ProxyMode`, `Window`, `Lightweight`, `Service`, and `File` to enhance log clarity and filtering.
