Prevent dependency building failure in Intel Dockerfile

[Growl1234]

Currently Intel Dockerfiles fails because Intel oneAPI toolkit lefts an invalid mpiifort wrapper that generates ifort command which doesn't exist in Intel oneAPI 2025.2; same as mpiicc and mpiicpc. This PR explicity set compilers to mpiicx, mpiicpx, and mpiifx through Docker's ENV.

Also, adds fail-fast: false to the workflow files with several jobs so that the jobs that should be successful are not interrupted by a single failing job.

Pull request overview

This PR addresses Intel oneAPI 2025.2 container build breakage by explicitly selecting the new Intel MPI compiler wrappers, and improves CI signal by preventing matrix jobs from being canceled early when one job fails.

Changes:

• Set CC/CXX/FC in Dockerfile.intel to mpiicx/mpiicpx/mpiifx (and install ca-certificates).
• Add strategy.fail-fast: false to selected multi-job GitHub Actions workflows so independent jobs continue running.
