fix(insert): place block attributes by their ATTDEF geometry, follow the block (#255)

Inserting a block piled every attribute at the origin: each AttributeEntity
was built from just tag + value with default geometry. Carry the full
AttributeDefinition through the attreq flow and build attributes with
AttributeEntity::from_definition, then apply the block's insertion transform
so each lands in WCS at its proper position / alignment / rotation.

Attributes are stored in world space, so moving the block must move them
too. The MOVE command already did (acadrust translate_insert); apply_grip
(grip-drag) and the Position X/Y/Z property edit now translate the
attributes by the same world delta so they no longer stay behind.

Rotate/scale/mirror of a block still don't carry the attributes — acadrust's
transform_insert has no attribute pass — tracked separately.
