CodeIssuesTask action

[martinherrerias]

Add a "build" step to the CI workflow, that runs the Code Analyser (CodeIssuesTask) and fails on errors. It should help keeping track of features of MATLAB that change over time. E.g. there's a couple of issues that used to be warnings, but became errors after R2025a:

• docs/DEMO_febio_0059_face_mask_loading.m used 1:size(Vr1) where Vr1 is a 2D array, which now requires an explicit 1:size(Vr1,1)
• JavaFrame has been dropped. I created a new issue for this (Drop dependency on findjobj #213), for now I hard-set the severity of the error back to "warning" and added an additional check that should warn for future uses of findjobj.
