[fix] engine qwant - return forbidden instead of showing parse error (#5377)

Apparently, setting padding on an input field and then clicking that
space created by the padding forces the seekbar cursor to jump to the
beginning of the input field instead of the actual text position.

By removing that padding, the search bar input automatically claims that
height for itself and thus clicking on the blank space moves the cursor to
the correct position.
