fix: draw-mode blank insertion supports mixed text+math selections
Expands the selection bounds to cover any partially-overlapped equation
before wrapping, rather than rejecting with an error. #blank[text $eq$]
is valid Typst so no special restructuring is needed once the equation
delimiters are fully included.
