C3D-PSATTR · Attach missing block attributes done

Creates AttributeReferences on the SS_BLOCK_22X17 reference from the definitions AttributeDefinitions, so the title block has editable attributes. Lists each tag/prompt/default.

C# payload

// Attach the missing attribute references to the SS_BLOCK_22X17 reference.
// Inserting a BlockReference does NOT instantiate attributes - each AttributeDefinition in the
// definition needs a matching AttributeReference appended to the reference and transformed by
// the reference's BlockTransform. Without this the block reports "no editable attributes".
// Host owns Tx - no using/Commit here.
