Enhance OpenCode form handling in AssistantPage

- Introduce a new model field in the OpenCode form to manage language model selection.
- Refactor the form handling logic to improve data loading and error management for OpenCode assistants.
- Update UI components to utilize ResourceSelectField for model and voice configuration, enhancing user experience.
- Clear form fields when creating new OpenCode entries to ensure a fresh start for users.
