fix(task-2): block_explode keeps the ATTRIB frame and writes into the owner layout

Browse Source 
Two silent wrong-place defects in the BURST path. An ATTRIB is an OCS
entity, so the TEXT that replaces it now carries extrusion/thickness with
insert/align_point; a mirrored reference (ATTRIB reflected to (0,0,-1),
INSERT +Z with yscale=-1) put the tag 50 units across the mirror axis with
a clean audit. Members and TEXTs now go into the INSERT's owner layout
(ezdxf get_layout, COM ObjectIdToObject(OwnerID)) instead of the current
space: a sheet title block exploded while Model was current duplicated
geometry into model space and then died on delete_entity headless, and on
COM landed the tag text in model space with ok: True. A reference nested
in a block definition is refused before any write on both engines.

Five regression tests (mirrored INSERT, sheet-owned INSERT with Model
current, nested INSERT, and the COM owner-block / nested-refusal call
shapes) fail on the previous commit and pass here.
