CI/CD fix

[Enmk]

Mostly focused on fixing CI/CD on Linux

• Using Ubuntu 22.04 and Ubuntu 24.04
• corresponding supported compilers
• Properly installing docker
• CompareRecursive fix for GCC-12 (fixes Unit tests build fails with GCC 12+ #425)

Closes #415 (supersedes)

[Copilot]

Pull Request Overview

This PR updates CI/CD workflows to support newer Ubuntu versions and compilers, improves Docker installation steps, and enhances the CompareRecursive utility with additional tests and type handling.

• Expanded CompareRecursive tests to cover characters, string types, and containers of strings
• Refactored utils_comparison.h to introduce L/R type aliases and handle char* via std::string_view
• Updated GitHub Actions across Windows, macOS, and Linux: added wildcard branch triggers, new compiler matrix entries, and Docker verification

• The top-level matrix no longer defines an os axis, which may lead to runs with an undefined OS; reintroduce os: [ubuntu-22.04, ubuntu-24.04] or ensure every matrix entry specifies os.

• Lines 91–92 duplicate the same assertions from lines 89–90; consider removing these redundant tests to keep the suite concise.
