feat: remove unused plugin version comparison and types, refactor proxy server to support authentication

- Deleted version comparison logic from `pkg/plugin/sign/version.go`.
- Removed unused types and constants from `pkg/plugin/types.go`.
- Updated `pkg/protocol/message.go` to remove plugin-related message types.
- Enhanced `pkg/proxy/http.go` and `pkg/proxy/socks5.go` to include username/password authentication for HTTP and SOCKS5 proxies.
- Modified `pkg/proxy/server.go` to pass authentication parameters to server constructors.
- Added new API endpoint to generate installation commands with a token for clients.
- Created database functions to manage installation tokens in `internal/server/db/install_token.go`.
- Implemented the installation command generation logic in `internal/server/router/handler/install.go`.
- Updated web frontend to support installation command generation and display in `web/src/views/ClientsView.vue`.
