fix: macos input focus issue in draggable regions

port fix from ipfs/ipfs-desktop#2983 to ensure interactive elements
(inputs, buttons, selects) work properly within electron's
draggable regions by setting app-region: no-drag

this resolves left-click focus issues on macos where inputs
were not receiving focus due to pointer events being blocked
