- Refactor network model types: replace `NetworkState` enum and phase-based NetworkStatus with a flat `NetworkStatus` struct. - Simplify API server ↔ plugin protocol: plugin `status()` returns runtime status only, API server owns configuration. - `NetworksService` `list()`/`create()` now return `NetworkResource` directly. - Remove lifecycle phase checks and state machine guards throughout CLI and API server. - `variant` is plugin-specific, it's not a required property. This PR replaces `NetworkPluginInfo` with a `plugin` name property on `NetworkConfiguration` and an `options` list similar to that for volumes. - Moved `variant` to the option list.
