refactor: disable write_todos functionality across chat and UI components

- Commented out the write_todos tracking and messaging logic in the stream_new_chat.py file.
- Disabled the import and usage of WriteTodosToolUI in the new-chat page component.
- Updated related logic in the active connectors tab to remove indexing state handling for write_todos.
- These changes are part of a temporary disablement of the write_todos feature for further evaluation.
