refactor(ChatNavbar, Navbar): simplify toggle functions and remove unused fullscreen hook

- Removed unnecessary useCallback functions for toggling assistants and topics, directly using the toggle functions instead.
- Eliminated the unused fullscreen hook import to clean up the code.
- Updated click handlers in the Navbar components for better readability and efficiency.
