Copy-paste *.k90 files still `include`d in dynamics/ and remove them.

Testing checklist

• Automatic CI (with unstructured)
• GPU on JeanZay (identical! reference job: https://gitlab.in2p3.fr/ipsl/projets/dynamico/dynamico/-/jobs/800326)
• modipsl/LAM

modipsl/LAM plots

As previously, we compare the current version (25) with the latest tested DYNAMICO version (24) and with the latest version of DYNAMICO used in the official modipsl/LAM implementation (01).
