✨(frontend) hide search and create doc button if not logged

- Added visibility checks for 'search' and 'New doc' buttons in the
document visibility tests.
- Updated LeftPanelHeader to conditionally render 'search' and 'New doc'
buttons based on user authentication status, improving user experience
and access control.
