fix: prevent Quick Tour from closing on window resize (#14)

The onClick={onClose} was on the outer fixed container, which could
receive mouse events during window resize. Moved it to the backdrop
div only — now only deliberate clicks on the dark overlay dismiss
the tour. The inner modal panel already stops propagation.
