feat: add config code entry screen to dashboard

Implement a screen for entering/managing the config `${code}` variable.

Enable this screen only when the platform is `metal` and there is a `${code}` variable in the `talos.config` kernel cmdline URL query.

Additionally, remove the "Delete" button and its functionality from the network config screen to avoid users accidentally deleting PlatformNetworkConfig parts that are not managed by the dashboard.

Add some tests for the form data parsing on the network config screen.
Remove the unnecessary lock on the summary tab - all updates come from the same goroutine.

Closes siderolabs/talos#6993.
