Replace direct npm.Client usage throughout the codebase with the proxy.Provider interface, enabling pluggable proxy backends. The deployer, API layer, and proxy manager now use provider-agnostic route management (ConfigureRoute/DeleteRoute) instead of NPM-specific API calls. Adds ProxyRouteID (string) to Instance model and ProxyProvider setting to Settings, with SQLite migrations for backward compatibility.
