Fix manual section/elevation annotation placement in non-plan views

Use get_default_annotation_matrix() for manual SECTION annotations so
the object is placed in the camera's annotation plane with the correct
rotation, matching how auto-generated section annotations are created.
Without this, annotations placed in elevation or section camera views
had identity rotation, causing the IFC representation to be in the wrong
coordinate system and failing to tessellate.

Also guard draw_edit_object_interface against non-IFC active objects to
prevent AssertionError during toolbar redraws, and skip IFC item edit
mode for ELEVATION/SECTION annotation types on placement.
