  2. BUG: fix handling for factorial(..., exact=False) for 0-dim array i… 

    …nputs (scipy#18754)

Also ensure `test_factorial{,2,k}_array_corner_cases` covers 0-dim. inputs correctly

Unfortunately, `np.array` will ignore an explicit `ndim=0` request and
happily give back a 1-dimensional result without complaint:
```
>>> np.array([1], ndmin=0, dtype=np.int64).ndim
1
```

This invalidated the original assumptions for these tests.

Additionally, we need to take care not to iterate over 0-dim arrays
(but also keep the tests with two elements in `content` correct),
that n.ravel().ndim == 1 even if n.ndim == 0, and that assert_equal
will not distinguish scalars from 0-dim arrays with the same value.

  7. MAINT: fix unuran licensing 

    * Fixes scipy#18765

* the offending unuran source file was removed
over at scipy/unuran#9,
and this PR updates us to point to latest `main`
version of submodule (caution: this pulls in a few
more commits from `main` we didn't have in original
`1.11.0` release)

* as noted over there, the (SciPy) testsuite appears to
pass just fine when this file is purged, likely
because we have `HAVE_DECL_LOG1P` always set, since
we require C99, and therefore unuran always uses
the version from `math.h` instead of in-house anyway
