Cap the fixed width on narrow viewports.

At Line [333], a hard 350px width can make the menu wider than a mobile viewport or narrow containing block. Add a responsive cap so long content wraps without causing horizontal overflow.

Proposed fix 
-  width: 350px;
+  width: min(350px, calc(100vw - 16px));

In `@packages/mantine/src/blocknoteStyles.css` around lines 333 - 334, Update the
fixed width declaration in the relevant menu style to cap its width at the
available containing-block or viewport width, while retaining the 350px maximum
on wider screens. Ensure long content can wrap without causing horizontal
overflow on narrow viewports.
