Subject: [PATCH] fix: update sim for SPEL 32-byte tree_id and submodule
 restore

TREE_ID_HEX updated from 24 to 32 bytes to match SPEL's tree_id format,
fixing stale payment account lookup that caused silent registration
failures (KeyNotFound error 8).

setup_and_run.sh now restores working tree files in all nested
submodules after git submodule update --init, which resets them.
