This PR fundamentally restructures the EasyTier GUI, introducing support for service mode and remote mode, transforming it from a simple desktop application into a powerful network management terminal. This change allows users to persistently run the EasyTier core as a background service or remotely manage multiple EasyTier instances, greatly improving deployment flexibility and manageability.
* refactor(gui): refactor gui to use RemoteClient trait and RemoteManagement component
* feat(gui): Add network config saving and refactor RemoteManagement
* add method to create NetworkConfig from TomlConfigLoader
* allow web export/import toml config file and gui edit toml config
* Extract the configuration file dialog into a separate component and allow direct editing of the configuration file on the web
QUIC proxy works like kcp proxy, it can proxy TCP streams and transfer data with QUIC.
QUIC has better congestion algorithm (BBR) for network with both high loss rate and high bandwidth.
QUIC proxy can be enabled by passing `--enable-quic-proxy` to easytier in the client side. The proxy status can be viewed by `easytier-cli proxy`.
also some improvements:
1. add magic dns option in gui.
2. allow icmp proxy fail on android
3. when no_tun is enabled, android do not start vpn service
