Merge PR #4102 first!

This PR fixes deprecations warnings raised while testing silx with numpy 2 for PR #4082 (some of the deprecation warnings were also raised by numpy 1.26):

• numpy.trapz renamed to trapezoid
• numpy.cross no longer supports 2d-vector input
• No longer possible to convert an array to a scalar (e.g., float(np.array([0])))

Closes #4097

@kif, @pierrepaleo please cautiously check the change in sift/alignment.
