* fix: route to new conversation when conversation not found
* Addressed PR feedback
* fix: Robust 404 conversation redirect handling
- Extract `isNotFoundError` utility to `utils/errors.ts` so axios stays
contained in one place rather than leaking into route/query layers
- Add `initialConvoQuery.isError` to the useEffect dependency array so
the redirect actually fires when the 404 response arrives after other
deps have already settled (was the root cause of the blank screen)
- Show a warning toast so users understand why they were redirected
- Add `com_ui_conversation_not_found` i18n key
* fix: Enhance error handling in getResponseStatus function
- Update the getResponseStatus function to ensure it correctly returns the status from error objects only if the status is a number. This improves robustness in error handling by preventing potential type issues.
* fix: Improve conversation not found handling in ChatRoute
- Enhance error handling when a conversation is not found by checking additional conditions before showing a warning toast.
- Update the newConversation function to include model data and preset options, improving user experience during error scenarios.
* fix: Log error details for conversation not found in ChatRoute
- Added logging for the initial conversation query error when a conversation is not found, improving debugging capabilities and error tracking in the ChatRoute component.
