Subject: [PATCH] feat: add support for Grok 4.3 model

- Added Grok 4.3 to the model selection form in settings.
- Updated `getModel` utility to handle Grok 4.3 selection, mapping it to `grok-latest`.
- Updated Grok 4.2 badge to "Stable" and Grok 4.3 to "New".
- Maintained support for both Grok 4.2 and Grok 4.3 based on user toggle.
