Fix #7998: Fix ExcludeFromDrawing filter corruption

In exclude_element_from_drawing, use " + " instead of "+" when
appending a GlobalId. Lark's unquoted_string regex
(/[^,.=><*!\s]+/) does not exclude '"' or '+', so
'"DEMOLISH"+GlobalId' was greedily matched as one token,
causing wrap_value to double-quote and escape the inner quotes
on the next round-trip through edit_element_filter.
Adding a space forces unquoted_string to stop at whitespace,
letting ESCAPED_STRING win the length tie on priority.

Also replace the enable_editing_element_filter +
edit_element_filter calls in ExcludeFromDrawing._execute with
a direct activate_drawing call; edit_element_filter was
unnecessarily re-exporting the pset and triggering the bug.
