Fix NewChatDialog to resolve the model from the dropdown default when the user has not
explicitly picked a model, allowing chat creation with the default model.
- Introduce `resolvedModel` that falls back to `defaultModelValue` when `selectedModel` is empty
- Use `resolvedModel` in submit handler and submit-disabled guard so the default model is accepted
- Add test for creating a session with the default model ("Use default" selected)
- Add test for creating a session with an explicitly chosen non-default model
- Update existing no-default test to verify the submit button stays disabled and no session is created
