- Fixes Issue pymc-devs#7878 - Replace pt.batched_dot(sqrt_quad.T, sqrt_quad.T) with pt.sum(sqrt_quad.T ** 2, axis=-1) - Computes squared norm per sample using modern PyTensor operations - Eliminates deprecation warnings and ensures future compatibility

Description
This PR replaces the deprecated
pt.batched_dotfunction with the preferredpt.sumoperation in the KroneckerNormal distribution's logprob calculation, addressing issue #7878.Problem
The current implementation uses
batched_dot, which is deprecated in PyTensor and triggers warnings. Deprecated functions may lead to future breakage and lower performance.Solution
Refactored the
KroneckerNormallogprob code to usept.sumwith explicit axis parameters, achieving the same functionality without relying on deprecated APIs.Tests
