Subject: [PATCH] fix: swap scriptPathControlBlocks[1] and [2] for three-leaf
 P2MR test vectors

In a tree structured as [leaf0, [leaf1, leaf2]], the control block for
spending a leaf must contain the sibling hashes along the Merkle path,
not the leaf's own hash. The current test vectors have the control blocks
for leaf1 and leaf2 swapped, causing them to include the spending leaf's
own hash as the first path element instead of its sibling's hash.

Fix swapped scriptPathControlBlocks entries for:
- p2mr_three_leaf_complex
- p2mr_three_leaf_alternative
