fix: preserve batch/input axes in output-axis block tensor concat spec
The output-axis concat spec "bt0,...; bt1,..." dropped batch and input
rows, causing shape errors when list block tensor components had input
or batch axes. Use the full spec "...|...-> bt0,...; ..." to broadcast
batch/input rows through concatenation.
Add test 13 exercising list block tensors with input-dim components.
