fix: improve VS Code LM API model name display

- Add 'name' property to vsCodeLmModels type in ExtensionMessage
- Map VS Code LM models to include name property when sending to webview
- Update VSCodeLM component to display model.name when available
- Falls back to vendor/family format if name is not provided

Fixes #8443
