[BUG] Free model shows credit notifications and profile mismatch

[Artyomkun]

Problem (one or two sentences)

After switching to a free model, the Zoo Code extension still shows the old model name in the settings UI and displays credit notifications, as if the user is on a paid plan. The model actually changes (confirmed by responses), but the billing system treats it as a paid model, creating a UI sync + billing mismatch.

Context (who is affected and when)

Any user who switches from a paid model to a free one in the Zoo Code extension will see this issue. The problem appears right after switching the model — the UI still shows the old paid model’s name, and the system starts asking for credits, even though the user is now on a free plan.

Reproduction steps

1. Open Zoo Code extension in your editor.
2. Go to settings and select a free model (e.g., minimax/minimax-m3-free).
3. Notice that the UI still shows the previously selected paid model name in the settings field — it does not update.
4. Go to your profile and check the active model — the profile shows it has been updated.
5. Send a request using the selected model.
6. Observe that the system asks for credits (credit notification appears), even though you are on a free model.
7. The model actually works (responses change), but the billing system treats it as a paid plan.

Expected result

The selected free model name should immediately appear in the settings UI. The system should not request or show credit notifications for a free model. The billing behavior should match the selected plan — free models must work without any credit or payment prompts.

Actual result

After switching to a free model, the settings UI still shows the old model name (it does not update). The profile shows the model has been updated. However, when sending a request, the system displays a credit notification and behaves as if the user is on a paid plan, even though the selected model is free.

Variations tried (optional)

I tested this only with Zoo Code's built-in provider. No other browsers or devices were used. The issue appeared when switching from a paid model to a free model within the same Zoo Code environment.
