refactor: Replace tokio::spawn with AsyncHandler::spawn for better task management

- Replace direct tokio::spawn calls with AsyncHandler::spawn across multiple modules
- Improves task lifecycle management and error handling consistency
- Affected files:
  - src-tauri/src/cmd/network.rs
  - src-tauri/src/core/core.rs
  - src-tauri/src/core/event_driven_proxy.rs
  - src-tauri/src/enhance/tun.rs
  - src-tauri/src/ipc/logs.rs
  - src-tauri/src/ipc/memory.rs
  - src-tauri/src/ipc/monitor.rs
  - src-tauri/src/ipc/traffic.rs
  - src-tauri/src/utils/network.rs
  - src-tauri/src/utils/resolve.rs

This change provides better control over async task spawning and helps prevent
potential issues with unmanaged background tasks.
