Use cet_make_exec() for phlex

[greenc-FNAL]

Factored out of #329.

• Use scoped phlex::phlexin tests for clarity

[Copilot]

Pull request overview

This PR modernizes the build system by migrating the phlex executable from add_executable() to cet_make_exec(), which is the cetmodules standard for creating executables. The migration creates a namespaced alias phlex::phlex that improves clarity and consistency throughout the test suite.

Changes:

• Converted phlex executable definition to use cet_make_exec() in phlex/app/CMakeLists.txt
• Updated all test references to use the namespaced phlex::phlex target instead of bare phlex
