I took a brief look, and the ImportError is very interesting.

Let's strace python with just the import:

     strace -ttf python3 -c 'from esys.lsm.util.FoundationPy import *'

...

14:10:56.209943 openat(AT_FDCWD, "/usr/lib/python3/dist-packages/esys/lsm/util/FoundationPy.so", O_RDONLY|O_CLOEXEC) = 3
-> good (kinda)
14:10:56.212278 openat(AT_FDCWD, "/usr/lib/python3.13/site-packages/esys/lsm/util/libFoundationPy.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
14:10:56.214012 openat(AT_FDCWD, "/lib/aarch64-linux-gnu/libFoundationPy.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
14:10:56.214587 openat(AT_FDCWD, "/usr/lib/aarch64-linux-gnu/libFoundationPy.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
14:10:56.215078 openat(AT_FDCWD, "/lib/libFoundationPy.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
14:10:56.215528 openat(AT_FDCWD, "/usr/lib/libFoundationPy.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)

All of these are correct, because libFoundationPy.so.0 is installed into
/usr/lib/python3/dist-packages/esys/lsm/util.  Note that for some reason,
python looks in /usr/lib/python3.13/... first: a python-version specific path.

Now, looking at the actual *.so files, using ldd:

/usr/lib/python3/dist-packages/esys/lsm/util/FoundationPy.so:
         libFoundationPy.so.0 => not found
         libboost_python313.so.1.83.0 => /lib/aarch64-linux-gnu/libboost_python313.so.1.83.0 (0x0000ffff836c0000)
         libpython3.13.so.1.0 => /lib/aarch64-linux-gnu/libpython3.13.so.1.0 (0x0000ffff82f20000)
[..]
/usr/lib/python3/dist-packages/esys/lsm/util/libFoundationPy.so:
         libFoundation-2.3.4.so => /lib/aarch64-linux-gnu/libFoundation-2.3.4.so (0x0000ffff81a40000)
         libboost_python313.so.1.83.0 => /lib/aarch64-linux-gnu/libboost_python313.so.1.83.0 (0x0000ffff819e0000)
         libpython3.13.so.1.0 => /lib/aarch64-linux-gnu/libpython3.13.so.1.0 (0x0000ffff81240000)
[..]

In my opinion, _both_ FoundationPy.so and libFoundationPy.so link to a
python-version specific library (libboost_python313.so.1.83.0). Therefore, they
shall NOT be installed into usr/lib/python3/dist-packages, but into
/usr/lib/python3.13/site-packages.

I would try rectifying this first, and then see if that solves the test failure.

Hope this helps.

Best,
Chris
