feat: handle case thread when original model deleted

[urmauur]

Describe Your Changes

1. ModelDropdown Component (index.tsx)

   • Imported atom from jotai.
   • Introduced a new atom modelDropdownStateAtom initialized to false.
   • Updated the state handling of the dropdown's open/close status to use the new atom.
   • Added a useEffect to sync the dropdown open state with the chatInputMode.

2. useCreateNewThread Hook

   • Removed import and usage of the useRecommendedModel hook.
   • Adjusted logic to set defaultModel without using recommendedModel.

3. useSendChatMessage Hook

   • Imported modelDropdownStateAtom and added logic to open the model dropdown if no model is selected when sending a chat message.

4. RichTextEditor Component

   • Added import for selectedModelAtom and used it to determine if the editor should reset after sending a message.

5. ChatInput Component

   • Added logic to automatically set the input box as active if no model is selected.
   • Slightly reorganized the activeSettingInputBox rendering logic to always include the setting input box with conditionally visible elements based on the selectedModel.
